The 2588G-->C mutation in the ABCR gene is a mild frequent founder mutation in the Western European population and allows the classification of ABCR mutations in patients with Stargardt disease. (1/312)

In 40 western European patients with Stargardt disease (STGD), we found 19 novel mutations in the retina-specific ATP-binding cassette transporter (ABCR) gene, illustrating STGD's high allelic heterogeneity. One mutation, 2588G-->C, identified in 15 (37.5%) patients, shows linkage disequilibrium with a rare polymorphism (2828G-->A) in exon 19, suggesting a founder effect. The guanine at position 2588 is part of the 3' splice site of exon 17. Analysis of the lymphoblastoid cell mRNA of two STGD patients with the 2588G-->C mutation shows that the resulting mutant ABCR proteins either lack Gly863 or contain the missense mutation Gly863Ala. We hypothesize that the 2588G-->C alteration is a mild mutation that causes STGD only in combination with a severe ABCR mutation. This is supported in that the accompanying ABCR mutations in at least five of eight STGD patients are null (severe) and that a combination of two mild mutations has not been observed among 68 STGD patients. The 2588G-->C mutation is present in 1 of every 35 western Europeans, a rate higher than that of the most frequent severe autosomal recessive mutation, the cystic fibrosis conductance regulator gene mutation DeltaPhe508. Given an STGD incidence of 1/10,000, homozygosity for the 2588G-->C mutation or compound heterozygosity for this and other mild ABCR mutations probably does not result in an STGD phenotype.  (+info)

Homozygosity mapping and linkage analysis demonstrate that autosomal recessive congenital hereditary endothelial dystrophy (CHED) and autosomal dominant CHED are genetically distinct. (2/312)

BACKGROUND: Congenital hereditary endothelial dystrophy (CHED) is a corneal dystrophy characterised by diffuse bilateral corneal clouding resulting in impaired vision. It is inherited in either an autosomal dominant (AD) or autosomal recessive (AR) manner. The AD form of CHED has been mapped to the pericentromeric region of chromosome 20. Another endothelial dystrophy, posterior polymorphous dystrophy (PPM), has been linked to a larger but overlapping region on chromosome 20. A large, Irish, consanguineous family with AR CHED was investigated to determine if there was linkage to this region. METHODS: The technique of linkage analysis with polymorphic microsatellite markers amplified by polymerase chain reaction (PCR) was used. In addition, a DNA pooling approach to homozygosity mapping was employed to demonstrate the efficiency of this method. RESULTS: Conventional genetic analysis in addition to a pooled DNA strategy excludes linkage of AR CHED to the AD CHED and larger PPMD loci. CONCLUSION: This demonstrates that AR CHED is genetically distinct from AD CHED and PPMD.  (+info)

On the role of kerato-epithelin in the pathogenesis of 5q31-linked corneal dystrophies. (3/312)

PURPOSE: Recently, the authors identified a gene, BIGH3, in which different mutations cause a group of hereditary corneal dystrophies: lattice type I and IIIA (CDLI and CDLIIIA), granular Groenouw type I (CDGGI), Avellino (CDA), and Reis-Bucklers' (CDRB). All these disorders are characterized by the progressive accumulation of corneal deposits with different structural organization. Experiments were conducted to determine the role of kerato-epithelin (KE), the product of BIGH3, in the pathogenesis of the diseases. METHODS: KE-15 and KE-2, two rabbit antisera raised against peptides from the 69-364 and 426 - 682 amino acid regions of KE respectively, were used for immunohistology of the corneas obtained after keratoplasty in six CDLI patients, three CDGGI patients, and one CDA patient. RESULTS: The nonamyloid deposits observed in CDGGI stained intensively with KE-15 and KE-2, whereas the amyloid deposits in all analyzed CDLI corneas reacted to KE-2 but not to KE-15. In the CDA cornea, where amyloid and nonamyloid inclusions were present, positive staining with both antisera was observed. CONCLUSIONS: Pathologic amyloid and nonamyloid deposits observed in CDLI, CDGGI-, and CDA-affected corneas are caused by KE accumulation. Different staining patterns of amyloid and nonamyloid deposits observed with antibodies against the amino and carboxyl termini of KE suggest that two mechanisms of KE misfolding are implicated in the pathogenesis of 5q31-linked corneal dystrophies.  (+info)

Apolipoproteins J and E co-localise with amyloid in gelatinous drop-like and lattice type I corneal dystrophies. (4/312)

AIMS: Apolipoprotein J (apoJ) and apolipoprotein E (apoE) are thought to contribute to amyloid formation in patients with Alzheimer's disease. The aim of this investigation was to discover whether or not these apolipoproteins associate with corneal amyloid in gelatinous drop-like corneal dystrophy (GDCD) and lattice corneal dystrophy type I (LCD-I). METHODS: Corneas from three eyes of three patients with GDCD and one eye of one patient with LCD-I were examined immunohistochemically using antibodies against apoJ and apoE. Two normal corneas were similarly examined. Tissue sections of brain from a patient with Alzheimer's disease were used as positive controls for the antibodies. For all negative controls, mouse IgG was used instead of the primary antibody. RESULTS: Intense apoJ and apoE immunoreactivities were found in congophilic amyloid deposits in GDCD and LCD-I. These deposits were located subepithelially in GDCD, and subepithelially and intrastromally in LCD-I. In GDCD, immunostaining of subepithelial amyloid with anti-apoJ was noticeably stronger than with anti-apoE. CONCLUSIONS: As in senile plaques in brain from a patient with Alzheimer's disease, apoJ and apoE co-localise with amyloid in corneas with GDCD and LCD-I.  (+info)

Corneal guttata associated with the corneal dystrophy resulting from a betaig-h3 R124H mutation. (5/312)

AIMS: To investigate the frequency of corneal guttata in patients with a corneal dystrophy resulting from an Arg124His (R124H) mutation of betaig-h3 gene. METHODS: Slit lamp examination was performed on 30 eyes with corneal dystrophy from a genetically confirmed betaig-h3 R124H mutation and on 50 age matched control eyes. The stage of the corneal dystrophy was classified as stage 0, I, or II and the degree of guttata was classified as none, mild, or severe. Specular microscopic examinations were performed to evaluate the morphology of the corneal endothelium. RESULTS: Slit lamp examination disclosed the presence of corneal guttata in 21 eyes (70%) of the 30 eyes with the corneal dystrophy, but in only one (2%) of the 50 eyes in the age matched control group (p<0.001, chi(2) with Yates's correction). Of the 12 eyes with stage I betaig-h3 R124H corneal dystrophy, seven had no corneal guttata and five had a mild degree of guttata. Of the 18 eyes with stage II, the degree of guttata was none in two, mild in nine, and severe in seven. The degree of corneal guttata was significantly related to the stage of the corneal dystrophy (p<0.0001, Kruskul-Wallis test ANOVA on ranks). There was no significant differences between eyes with betaig-h3 R124H corneal dystrophy and normal eyes in cell density, coefficient of variation, and cell hexagonality of corneal endothelium. CONCLUSION: Corneal guttata are one of the characteristics of the corneal dystrophy resulting from betaig-h3 R124H mutation.  (+info)

Acute hydrops in the corneal ectasias: associated factors and outcomes. (6/312)

PURPOSE: To identify factors associated with the development of hydrops and affecting its clinical outcome. METHODS: Chart review of all patients with acute hydrops seen by a referral cornea service during a 2.5-year period between June 1996 and December 1998. RESULTS: Twenty-one patients (22 eyes) with acute hydrops were seen. Nineteen patients had keratoconus, 2 had pellucid marginal degeneration, and 1 had keratoglobus. Twenty-one of 22 (95%) eyes had seasonal allergies and 20 of 22 (91%) eyes had allergy-associated eye-rubbing behavior. Six of 22 (27%) had a diagnosis of Down's syndrome. Six patients were able to identify a traumatic inciting event: vigorous eye rubbing in 4 and traumatic contact lens insertion in 2. The affected area ranged from 7% to 100% of the corneal surface area and was related to disease duration and final visual acuity. Proximity of the area of edema to the corneal limbus ranged from 0 to 2.3 mm and was also related to prognosis. Three serious complications were observed: a leak, an infectious keratitis, and an infectious keratitis and coincidental neovascular glaucoma. Various medical therapies did not differ significantly in their effect on outcome, and ultimately 4 (18%) of 22 patients underwent penetrating keratoplasty. Best-corrected visual acuity was equal to or better than prehydrops visual acuity in 5 of the 6 patients in whom prehydrops visual acuity was known, without corneal transplantation. CONCLUSIONS: Allergy and eye-rubbing appear to be important risk factors in the development of hydrops. Visual results are acceptable in some patients without surgery. Close observation allows for the early detection and treatment of complications such as perforation and infection.  (+info)

Ultrastructural localization of sulfated and unsulfated keratan sulfate in normal and macular corneal dystrophy type I. (7/312)

Keratan sulfate (KS) proteoglycans are of importance for the maintenance of corneal transparency as evidenced in the condition macular corneal dystrophy type I (MCD I), a disorder involving the absence of KS sulfation, in which the cornea becomes opaque. In this transmission electron microscope study quantitative immuno- and histochemical methods have been used to examine a normal and MCD I cornea. The monoclonal antibody, 5-D-4, has been used to localize sulfated KS and the lectin Erythrina cristagalli agglutinin (ECA) to localize poly N -acetyllactosamine (unsulfated KS). In normal cornea high levels of sulfated KS were detected in the stroma, Bowman's layer, and Descemet's membrane and low levels in the keratocytes, epithelium and endothelium. Furthermore, in normal cornea, negligible levels of labeling were found for N -acetyllactosamine (unsulfated KS). In the MCD I cornea sulfated KS was not detected anywhere, but a specific distribution of N -acetyllactosamine (unsulfated KS) was evident: deposits found in the stroma, keratocytes, and endothelium labeled heavily as did the disrupted posterior region of Descemet's membrane. However, the actual cytoplasm of cells and the undisrupted regions of stroma revealed low levels of labeling. In conclusion, little or no unsulfated KS is present in normal cornea, but in MCD I cornea the abnormal unsulfated KS was localized in deposits and did not associate with the collagen fibrils of the corneal stroma. This study has also shown that ECA is an effective probe for unsulfated KS.  (+info)

Late onset lattice corneal dystrophy with systemic familial amyloidosis, amyloidosis V, in an English family. (8/312)

AIMS: To establish a clinical and molecular diagnosis in a family with late onset lattice corneal dystrophy. METHODS: Linkage analysis, single strand conformation polymorphism (SSCP) analysis, and direct sequencing of genomic DNA were performed. A review of the patients' clinical symptoms and signs was undertaken. RESULTS: Linkage to chromosome 9q34 was established and a mutation in the gelsolin gene was found in affected individuals. Numerous symptoms experienced by the patients were attributable to this mutation. CONCLUSION: A diagnosis of amyloidosis type V (familial amyloidosis, Finnish type, FAF/Meretoja syndrome/gelsolin related amyloidosis) was made. This is the first case of amyloidosis type V described in the UK. This emphasises the importance of recognition of the extraocular manifestations of eye disease both in the diagnosis and management of the patient. In addition, these findings can help molecular geneticists in their search for disease-causing mutations.  (+info)

Lattice corneal dystrophy type I is an eye disorder that affects the clear, outer covering of the eye called the cornea. The cornea must remain clear for an individual to see properly; however, in lattice corneal dystrophy type I, protein clumps known as amyloid deposits cloud the cornea, which leads to vision impairment. The cornea is made up of several layers of tissue, and in lattice corneal dystrophy type I, the deposits form in the stromal layer. The amyloid deposits form as delicate, branching fibers that create a lattice pattern.. Affected individuals often have recurrent corneal erosions, which are caused by separation of particular layers of the cornea from one another. Corneal erosions are very painful and can cause sensitivity to bright light (photophobia). Lattice corneal dystrophy type I is usually bilateral, which means it affects both eyes. The condition becomes apparent in childhood or adolescence and leads to vision problems by early adulthood. ...
Gelatinous drop-like corneal dystrophy, also known as amyloid corneal dystrophy, is a rare form of corneal dystrophy. The disease was described by Nakaizumi as early as 1914. The main pathological features in this dystrophy are mulberry-shaped gelatinous masses beneath the corneal epithelium. Patients suffer from photophobia, foreign body sensation in the cornea. The loss of vision is severe. The amyloid nodules have been found to contain lactoferrin, but the gene encoding lactoferrin is unaffected. This form of corneal amyloidosis appears to be more frequent in Japan. A number of mutations causing this disease have been described in the M1S1 (TACSTD2) gene encoding Tumor-associated calcium signal transducer 2, but not all patients have these mutations, suggesting involvement of other genes. Recurrence within a few years occurs in all patients following corneal transplantation. Soft contact lenses are effective in decreasing recurrences. Nakaizumi, K. : A rare case of corneal dystrophy. Acta. ...
PURPOSE: To characterize the molecular defect in the TGFBI gene in a Chinese family affected with an atypical lattice corneal dystrophy.. DESIGN: Case report and experimental study.. METHODS: Molecular genetic analysis was performed on the DNA extracted from peripheral leucocytes from a Chinese family with atypical lattice corneal dystrophy. Fifty normal unrelated subjects of Chinese origin were used as controls. All exons of the TGFBI gene were amplified by polymerase chain reaction and directly sequenced.. RESULTS: Bilateral, symmetrical, ridgy round pattern of opacities with uneven surfaces and thin lattice lines were noted in the proband. Analysis of exon 14 revealed a heterozygous T to A transition on codon 625. The mutation was not detected in the unaffected family member and 50 unaffected individuals.. CONCLUSIONS: The novel TGFBI gene mutation (V625D) is associated with an early,onset variant of lattice corneal dystrophy. This case highlights the utility of molecular genetic analysis in ...
Purpose: This study was designed to investigate whether matrix metalloproteinases (MMPs) play a pivotal role in the development of TGFBI-Arg124Cys lattice corneal dystrophy type I (LCDI) using an ex vivo model of LCDI corneal epithelial cell cultures and corneal tissue excised from an LCDI patient.. Methods: To initially determine whether the dissolution of Bowmans layer is apparent in an LCDI affected cornea an H&E stain was carried out on sections of a corneal button excised from a patient suffering from TGFBI-Arg124Cys LCDI. Immunohistochecimstry (IHC) was also carried out to determine whether there is a localisation of MMPs around Bowmans layer. To confirm the induction of MMPs due to the presence of the TGFBI-Arg124Cys mutant allele qRT-PCR was carried out on LCDI corneal epithelial cultures and expression levels were compared to those observed in wild type corneal epithelial cultures.. Results: H&E staining confirmed dissolution of Bowmans layer in an LCDI affected cornea while IHC ...
PURPOSE: To report the presence of the R124H mutation in two Spanish families with Avellino corneal dystrophy (ACD). METHODS: Two families with subjects who presented biomicroscopic features of ACD were included in this study. They have no relatives
Lattice Corneal Dystrophy is associated with painful recurrent corneal erosions and amyloid corneal opacities induced by transforming growth factor β induced protein (TGFBIp) that impairs vision. The exact mechanism of amyloid fibril formation in Corneal Dystrophy is unknown but has been associated with destabilizing mutations in the fourth fasciclin 1 (Fas1-4) domain of TGFBIp. The green tea compound Epigallo-catechin gallate (EGCG) has been found to inhibit fibril formation of various amyloidogenic proteins in vitro. In this study we investigated the effect of EGCG as a potential treatment in Lattice Corneal Dystrophy (LCD) using Fas1-4 with the naturally occurring LCD-inducing A546T mutation. A few molar excess of EGCG were found to inhibit fibril formation in vitro by directing Fas1-4 A546T into stable EGCG-bound protein oligomers. Incubation with two molar equivalent EGCG led to a 4-fold reduction in the aggregates membrane disruptive potential, potentially indicative of significantly ...
Schnyder crystalline corneal dystrophy (SCCD, MIM 121800) is a rare autosomal dominant disease characterized by progressive opacification of the cornea resulting from the local accumulation of lipids, and associated in some cases with systemic dyslip
In this study, we have identified two novel homozygous mutations from 3 unrelated GDLD patients with a phenotype well co-segregated with the genotype within their respective families. The insertional mutation of TACSTD2 that was found in 2 of the GDLD patients may have resulted from a flame-shift amino acid alteration with premature termination (p.Ile281SerfsX23) within the transmembrane domain. A substitutive mutation found in 1 of the GDLD patients may have resulted from a nonsense mutation (p.Tyr225X) within a region between the thyroglobulin type-1 and transmembrane domains. The transmembrane domain should support the hydrophobic scaffold which may be fundamental to the membrane binding property of this protein. However, and as far as we know, such a domain structure is only a computationally speculated model from the primary amino acid structure of this protein. Therefore, the subcellular localization of both the wild-type and mutated TACSTD2 proteins was experimentally determined in this ...
Corneal dystrophy, lattice type 3A (CDL3A) [MIM:608471]: A form of lattice corneal dystrophy, a class of inherited stromal amyloidoses characterized by pathognomonic branching lattice figures in the cornea. CDL3A is characterized by decreased visual acuity, and the presence of thick, ropy branching lattice lines and accumulations of amyloid deposits in the corneal stroma. Systemic amyloidosis is absent. CDL3A clinically resembles to lattice corneal dystrophy type 3, but differs in that its age of onset is 70 to 90 years. It has an autosomal dominant inheritance pattern. {ECO:0000269,PubMed:15790870, ECO:0000269,PubMed:9497262}. Note=The disease is caused by mutations affecting the gene represented in this entry ...
Disease: (OMIM: 217400 217700 610206 613268) Defects in SLC4A11 are the cause of corneal dystrophy and perceptive deafness (CDPD) [MIM:217400]; also known as corneal dystrophy and sensorineural deafness or Harboyan syndrome. CDPD consists of congenital corneal endothelial dystrophy and progressive perceptive deafness. Inheritance is autosomal recessive; Defects in SLC4A11 are the cause of corneal endothelial dystrophy type 2 (CHED2) [MIM:217700]; also known as congenital hereditary endothelial dystrophy of cornea. This bilateral corneal dystrophy is characterized by corneal opacification and nystagmus. Inheritance is autosomal recessive; Defects in SLC4A11 are the cause of corneal dystrophy Fuchs endothelial type 4 (FECD4) [MIM:613268]; also known as Corneal dystrophy Fuchs endothelial late-onset. It is an ocular disorder caused by loss of endothelium of the central cornea. It is characterized by focal wart-like guttata that arise from Descemet membrane and develop in the central cornea, ...
Congenital stromal corneal dystrophy (CSCD), also called Witschel dystrophy, is an extremely rare, autosomal dominant form of corneal dystrophy. Only 4 families have been reported to have the disease by 2009. The main features of the disease are numerous opaque flaky or feathery areas of clouding in the stroma that multiply with age and eventually preclude visibility of the endothelium. Strabismus or primary open angle glaucoma was noted in some of the patients. Thickness of the cornea stays the same, Descemets membrane and endothelium are relatively unaffected, but the fibrills of collagen that constitute stromal lamellae are reduced in diameter and lamellae themselves are packed significantly more tightly. CSCD is associated with a mutation in the gene DCN that encodes the protein decorin, located at chromosome 12q22. The disorder is inherited in an autosomal dominant manner, which indicates that the defective gene responsible for a disorder is located on an autosome (chromosome 12 is an ...

Hereditary mutations in the transforming growth factor beta induced (TGFBI) gene cause phenotypically distinct corneal dystrophies characterized by protein deposition in cornea. We show here that the Arg555Trp mutant of the fourth fasciclin 1 (FAS1-4) domain of the protein (TGFBIp/keratoepithelin/betaig-h3), associated with granular corneal dystrophy type 1, is significantly less susceptible to proteolysis by thermolysin and trypsin than the WT domain. High-resolution liquid-state NMR of the WT and Arg555Trp mutant FAS1-4 domains revealed very similar structures except for the region around position 555. The Arg555Trp substitution causes Trp555 to be buried in an otherwise empty hydrophobic cavity of the FAS1-4 domain. The first thermolysin cleavage in the core of the FAS1-4 domain occurs on the N-terminal side of Leu558 adjacent to the Arg555 mutation. MD simulations indicated that the C-terminal end of helix alpha3 containing this cleavage site is less flexible in the mutant domain, ...
Aims: To characterise the role of the carbohydrate sulfotransferase gene (CHST6) in macular corneal dystrophy (MCD) in Czech patients. Methods: The coding region of the CHST6 gene was directly sequenced in ten affected and five unaffected members from eight apparently unrelated MCD families. The type of MCD was determined by enzyme-linked immunosorbent assay of antigenic keratan sulfate (KS) in serum and by immunohistochemical staining of corneas with monoclonal anti-KS antibody. Results: The following changes in the coding sequence of the CHST6 gene were observed; homozygous mutation of c.1A,T (p.M1?); homozygous mutation c.599T,G (p.L200R); compound heterozygosity for c.599T,G and c.614G,A (p.R205Q); compound heterozygosity for c.494G,A (p.C165Y) and c.599T,G; heterozygous c.599T,G mutation and no other change in the coding sequence. One proband exhibited no changes. The pathogenic mutation c.599T,G (p.L200R) was in allelic association with the c.484C,G (p.R162G) polymorphism. Nine patients ...

AU - Kim, Eung Kweon. PY - 2012/6/1. Y1 - 2012/6/1. N2 - Granular corneal dystrophy type 2 (GCD2) is an autosomal dominant disease caused by a R124H point mutation in the transforming growth factor-β-induced gene (TGFBI). However, the cellular role of TGFBI and the regulatory mechanisms underlying corneal dystrophy pathogenesis are still poorly understood. Lysophosphatidic acid (LPA) refers to a small bioactive phospholipid mediator produced in various cell types, and binds G protein-coupled receptors to enhance numerous biological responses, including cell growth, inflammation, and differentiation. LPA levels are elevated in injured cornea and LPA is involved in proliferation and wound healing of cornea epithelial cells. Accumulating evidence has indicated a crucial role for LPA-induced expression of TGFBI ...

Your cornea is the clear part of the front of the eye. Corneal dystrophies are common genetic conditions which cause changes to your cornea without any inflammation, infection or other eye disease. Corneal dystrophies affect the clearness of your cornea and usually involve both eyes. Although they can often get worse over time, normally this happens very slowly. Many corneal dystrophies develop so slowly that they may never get to a point where they affect your vision.

Results. Phenotype of patients. We analyzed the presence of TGFBI gene mutations in two Spanish families affected by autosomal-dominant CD. Family CD1 was diagnosed with lattice type I CD which affected four generations. Members of this family were from the province of Albacete. The second family (CD2) was affected by granular type I CD and also encompassed four generations from the province of Valencia. The disease was bilateral in all patients. Five (50%) lattice type I CD patients were male and five patients (50%) were female. In the case of granular type I CD, three affected subjects were male and three were female. The age at diagnosis for lattice type I CD patients ranged 3-46 years (mean 17.25 years) and for granular CD patients, the age range was 26-53 years. Two patients (Figure 1A, subjects III:6 and IV:1 from families CD1 and CD2, respectively) were diagnosed during this study. The oldest studied patients in family CD1 were two siblings (Figure 1A, II:1 and II:2), who were 70 and 72 ...
Biettis crystalline dystrophy is a rare form of tapetoretinal degeneration associated with numerous glittering deposits on the retina of the posterior pole and in the limbic part of the cornea. The case of a patient with Biettis crystalline dystrophy followed-up for more than 5 years is described together with the changes seen during progression of the dystrophy. The patient was examined for the first time at the age of 27. At the last visit, marked impairment of night vision had developed, while there was no change in visual acuity. Ophthalmoscopic examination revealed that retinal crystals at the posterior pole were reduced in number, pigmented atrophy was more profound and that wide areas of choriocapillary atrophy had developed. There was a reduction in amplitude of the electroretinogram and the development of incomplete annular paracentral scotomas in the visual field. This case confirms that the symptoms of Biettis dystrophy develop late and that progression of the dystrophy involves atrophy of
The role of lipids in the process of embryonic development of Caenorhabditis elegans is still poorly understood. Cytochrome P450s, a class of lipid-modifying enzymes, are good candidates to be involved in the production or degradation of lipids essential for development. We investigated two highly similar cytochrome P450s in C. elegans, cyp-31A2 and cyp-31A3, that are homologs of the gene responsible for Bietti crystalline corneoretinal dystrophy in humans. Depletion of both cytochromes either by RNAi or using a double deletion mutant, led to the failure of establishing the correct polarity of the embryo and to complete the extrusion of the polar bodies during meiosis. In addition, the egg became osmotic sensitive and permeable to dyes. The phenotype of cyp-31A2 or cyp-31A3 is very similar to a class of mutants that have polarization and osmotic defects (POD), thus the genes were renamed to pod-7 and pod-8, respectively. Electron microscopic analysis demonstrated that the activity of pod-7/pod-8 ...

PURPOSE: To report the genetic findings in a Chinese patient diagnosed with gelatinous droplike corneal dystrophy (GDLD).. DESIGN: Case report and experimental study.. METHODS: Molecular genetic analysis was performed on the DNA extracted from peripheral leukocytes from a Chinese patient with GDLD and his unaffected parents. Fifty healthy, unrelated, Chinese participants were used as control subjects. The M1S1 gene was amplified by polymerase chain reaction and directly sequenced.. RESULTS: The patient was clinically diagnosed with GDLD. Direct sequencing of the M1S1 gene revealed heterozygous changes in both alleles, a novel Y184C mutation on one allele and a Q118X mutation on the other that was reported as a founder mutation in the Japanese population. The patient′s unaffected parents showed only the heterozygous Q118X or Y184C mutation. The mutation was not detected in the 50 unaffected subjects.. CONCLUSIONS: This is the first genetic analysis of a Chinese patient with GDLD. Because the ...

Corneal dystrophy, Schnyder type (SCCD) [MIM:121800]: A form of stromal corneal dystrophy characterized by corneal clouding, resulting from abnormal deposition of cholesterol and phospholipids, and decreased visual acuity. Typically, ring-shaped yellow-white opacities composed of innumerable fine needle-shaped crystals form in Bowman layer and the adjacent anterior stroma of the central cornea. The crystals usually remain in the anterior third of the cornea. The corneal epithelium and endothelium as well as Descemet membrane are spared. {ECO:0000269,PubMed:17668063, ECO:0000269,PubMed:17962451, ECO:0000269,PubMed:18176953, ECO:0000269,PubMed:19429578, ECO:0000269,PubMed:19649163, ECO:0000269,PubMed:20489584, ECO:0000269,PubMed:20505825, ECO:0000269,PubMed:23169578, ECO:0000269,PubMed:23374346}.

Corneal dystrophy is caused by mutations in the genes Corneal dystrophy is a hereditray disease caused by mutations in the genes coding for proteins in the cornea. So far, more than 60 different mutations are found in the gene encoding the protein Transforming Growth Factor Beta-Induced protein (TGFBIp), all of which result in a corneal clouding and thereby severe visual impairment and pain for the patient.. With the new research project, the researchers want to study the molecular mechanisms underlying the deposition of TGFBIp. The researchers will seek to determine the functions of the TGFBIp as a mean to better understand the pathology of corneal dystrophy.. Based on the biochemical studies, the researchers also plan to make relevant animal models, which are expected to contribute to a better understanding of the disease, and thereby ultimately to contribute to the development of a non-surgical treatment.. The project takes place at the Department of Molecular Biology and Genetics at Aarhus ...
Diagnosis:. A veterinary ophthalmologist can diagnose corneal dystrophy through a routine slit lamp examination. These anomalies, if present, can also be detected in a CERF exam. Because some forms of corneal dystrophy can onset later in life, a normal CERF exam does not guarantee that the dog will not later develop a hereditary eye problem.. Treatment:. No medication will dissolve the opacity resulting from a corneal dystrophy. Surgical removal of the dystrophic area may temporarily decrease the opacity in cases of epithelial dystrophy. However, new opaque area will often reform once the cornea has healed. Many of the corneal dystrophies are mild, non painful, and do not require treatment. If corneal ulcers develop they are generally treated with antibiotic ointment. Corneal transplants or corneal grafts may be options for some dogs with more severe symptoms.

Corneal dystrophy and perceptive deafness is a rare autosomal recessive disease which is caused by pathogenic variants in the gene SLC4A11. It has been reported across multiple ethnicities. Clinical features include corneal clouding that is present from birth or early infancy, and progressive hearing loss that develops between late childhood and early adulthood. Some patients will not develop hearing loss. At the moment, it is not known why some patients develop hearing loss and others do not. Life expectancy is not affected. For information about carrier frequency and residual risk, please see the Expanded Carrier Screen brochure.. ...

Mutations in the human TGFBI gene encoding TGFBIp have been linked to protein deposits in the cornea leading to visual impairment. The protein consists of an N-terminal Cys-rich EMI domain and four consecutive fasciclin 1 (FAS1) domains. We have compared the stabilities of wild-type (WT) human TGFBIp and six mutants known to produce phenotypically distinct deposits in the cornea. Amino acid substitutions in the first FAS1 (FAS1-1) domain (R124H, R124L, and R124C) did not alter the stability. However, substitutions within the fourth FAS1 (FAS1-4) domain (A546T, R555Q, and R555W) affected the overall stability of intact TGFBIp revealing the following stability ranking R555W,WT,R555Q,A546T. Significantly, the stability ranking of the isolated FAS1-4 domains mirrored the behavior of the intact protein. In addition, it was linked to the aggregation propensity as the least stable mutant (A546T) forms amyloid fibrils while the more stable variants generate non-amyloid amorphous deposits in vivo. ...

Purpose: : Recent advances in molecular genetics have linked the mutations in BIGH3 gene with various types of corneal dystrophy characterized by the abnormal amyloid and/or non-amyloid deposits in corneal stroma. To understand the pathogenesis of BIGH3-related corneal dystrophies, in vitro studies with recombinant BIGH3 mutant proteins were conducted to investigate the molecular properties responsible for amyloid/fibril formation. Methods: : A serum-free medium system was used for the large-scale expression of recombinant wild-type, R124C and R555W BIGH3 proteins in 293 cells. To facilitate protein purification, a (His)6-tag motif was inserted after the sequence encoding the signal peptide of BIGH3 in expression plasmids and a strep-tag II motif was inserted before the RGD sequence in the C-terminus. Ni+-NTA and strep-tactin chromatographies were used to purify expressed proteins. Limited proteolysis, intrinsic fluorescence and circular dichroism (CD) spectroscopy were used to characterize the ...

This gene encodes an RGD-containing protein that binds to type I, II and IV collagens. The RGD motif is found in many extracellular matrix proteins modulating cell adhesion and serves as a ligand recognition sequence for several integrins. This protein plays a role in cell-collagen interactions and may be involved in endochondrial bone formation in cartilage. The protein is induced by transforming growth factor-beta and acts to inhibit cell adhesion. Mutations in this gene are associated with multiple types of corneal dystrophy.

Congenital stromal corneal dystrophy is caused by mutations in the DCN gene. This gene provides instructions for making a protein called decorin, which is involved in the organization of collagens. Collagens are proteins that strengthen and support connective tissues such as skin, bone, tendons, and ligaments. In the cornea, well-organized bundles of collagen make the cornea transparent. Decorin ensures that collagen fibrils in the cornea are uniformly sized and regularly spaced.. Mutations in the DCN gene lead to the production of a defective version of decorin. This abnormal protein interferes with the organization of collagen fibrils in the cornea. As poorly arranged collagen fibrils accumulate, the cornea becomes cloudy. These corneal changes lead to reduced visual acuity and related eye abnormalities. ...
As with the other endothelial dystrophies, the initial efforts to identify the genetic basis of late-onset FECD consisted of linkage analyses and screening of genes implicated in other corneal endothelial dystrophies. Following the identification of SLC4A11 mutations in individuals with CHED2, Vithana and colleagues screened SLC4A11 in 89 individuals with sporadic and familial FECD, identifying four individuals with presumed pathogenic variants (three missense and one frameshift) [9]. However, as three of the four cases were sporadic, and no affected family members of the fourth individual were available for testing, segregation was not demonstrated for any of the variants [9]. To support their contention that the identified variants were functionally significant, the authors investigated the effects of the 3 heterozygous missense mutations on protein expression and localization. The demonstration of significantly decreased expression of two of the three mutant proteins in transfected HEK cells ...
PURPOSE To investigate whether corneal epithelial cells of individuals with lattice corneal dystrophy (LCD) possess an intrinsic defect. DESIGN Retrospective case-control study. METHODS The medical charts of nine individuals with LCD and those of 14 patients with keratoconus and 11 patients with corneal leukoma (controls), all of whom underwent penetrating keratoplasty (PKP) in one eye at Yamaguchi University Hospital between February 1998 and November 2001, were examined for the time for epithelial resurfacing after surgery. RESULTS The time required for resurfacing of the corneal epithelium after PKP was significantly greater in LCD patients (8.56 +/- 4.95 days, mean +/- SD) than in patients with either keratoconus (1.71 +/- 0.91 days, P = .006) or corneal leukoma (3.00 +/- 1.95 days, P = .03). CONCLUSIONS Corneal epithelial wound healing was delayed in LCD patients after PKP, suggesting that the keratoepithelin gene mutations responsible for this condition affect corneal epithelial cells.

Congenital hereditary endothelial dystrophy (CHED) is an inherited disorder of the corneal endothelium characterised by bilateral non-inflammatory corneal clouding ranging from a diffuse haze to a ground-glass appearance. CHED can be inherited in an autosomal dominant (CHED1) or recessive (CHED2) manner. CHED2 usually presents at birth or early infancy. Bilateral corneal clouding can lead to visual impairment often accompanied by nystagmus in CHED2 patients requiring corneal transplantation.1 Mutations in the solute carrier family 4 member 11 (SLC4A11) gene have been identified in most patients with CHED2. With PCR sequencing of the entire coding and putative promoter regions of SLC4A11, there were, however, some clinically confirmed CHED2 patients with undetected SLC4A11 mutations.2 ...
Recurrent corneal erosions are a common complication of superficial corneal wounds. They most commonly arise following a trauma, in association with various corneal dystrophies, or are idiopathic.. The main aim of this thesis was to investigate two hereditary corneal diseases with recurrent erosions in order to find out if they had been described before, and more specifically to describe the clinical picture and the morphological changes, differentiate them from other known autosomal dominant corneal dystrophies with a clinical resemblance, and to exclude genetic linkage to known corneal dystrophies with autosomal-dominant inheritance and a clinical resemblance.. The thesis is based on two families of subjects belonging to different phenotypes. The subjects from Småland (Dystrophia Smolandiensis) belonged to a six-generation family, which included 171 individuals of whom 44 were affected individuals, and the family from Hälsingland (Dystrophia Helsinglandica) included sevengenerations of 342 ...
Background: Phototherapeutic keratectomy (PTK) has been employed as a surgical tool to treat corneal disease for more than 10 years. The laser has made it possible to remove superficial corneal opacities and thereby restore vision. The 193 nm ultraviolet light separates molecules and splits molecules in biological tissue, thereby ablating it. About 0.25 ╡m of tissue is ablated by each pulse. The development of the excimer laser technique has been fast. It has principally focused on refractive surgery but has also benefited PTK. Corneal dystrophies: The ability to delay or postpone corneal grafting in superficial corneal dystrophies represents a very important achievement. Map-dot-fingerprint dystrophy or basal membrane dystrophy is a common indication for PTK. Other dystrophies such as Meesmans, Reis-Bⁿcklers, Thiel-Benkes, granular, macular, lattice and Schnyders can be treated, although with differing degrees of success and varying rates of recurrence. Subepithelial scarring in Fuchs ...

Nuclear mRNA transport is often thought of in terms of translocation through the nuclear pore, but mRNA export also requires intranuclear progression of transcripts from the gene to the nuclear pore. In some genetic diseases, failed export of a mutant mRNA is critical to the phenotype, yet typically it is not well understood how nuclear export is impeded or whether mutant mRNA accumulates at a specific point within the nuclear structure. In fact, the examination of mRNA blocked at a specific step in export may help illuminate the path whereby mRNA normally transits from the gene to the nuclear pore. The analysis of human disease gene mutations that impact nuclear metabolism of the mRNA provides an avenue to study both disease pathogenesis and the interrelationship between nuclear structure and steps in mRNA biogenesis. In addition, the study of naturally occurring disease alleles in patient cells provides the advantage that the mutant mRNA is expressed in a normal structural and physiological ...

Macular corneal dystrophy (MCDC; sometimes also Fehr corneal dystrophy) is a rare pathological condition affecting the stroma of cornea. The first signs are usually noticed in the first decade of life, and progress afterwards, with opacities developing in the cornea. There is also a predisposition to developing painful recurrent corneal erosions. MCDC is inherited in autosomal recessive fashion and is thought to be caused by the lack or abnormal confuguration of keratan sulfate. Most cases of MCD are caused by mutations in CHST6 gene. The condition was first described by Arthur Groenouw in 1890.. Alan N.

PURPOSE: To investigate the functional role that the zinc e-box binding homeobox 1 (ZEB1) gene, which underlies the genetic basis of posterior polymorphous corneal dystrophy 3 (PPCD3), plays in corneal endothelial cell proliferation, apoptosis, migration, and barrier function. METHODS: A human corneal endothelial cell line (HCEnC-21T) was transfected with siRNA targeting ZEB1 mRNA. Cell proliferation, apoptosis, migration, and barrier assays were performed: Cell proliferation was assessed with cell counting using a hemocytometer; cell apoptosis, induced by either ultraviolet C (UVC) radiation or doxorubicin treatment, was quantified by measuring cleaved caspase 3 (cCASP3) protein levels; and cell migration and barrier function were monitored with electric cell-substrate impedance sensing (ECIS ...
Myotonic Dystrophy (DM) a multi-systemic disorder, is the most common adult muscular dystrophy form. Among the pathological manifestations observed in the skeletal musculature include non-muscle defects as insulin resistance. Aberrant regulation has postulated involvement in the disease progression of DM1 specific insulin resistance characteristic of the disorder. RNA binding proteins involved in alternative splicing affect inclusion of spliced exons by binding to sequence specific cis-acting elements in pre-mRNA. The MBNL as well as the CELF class of proteins regulate alternative splicing of pre-mRNA insulin receptor (IR) by working antagonistically as a result of their distinct pre-mRNA binding sites. Of the two isoforms of insulin receptor (IR), the expression of the B isoform is affected to yield the non-muscle, low signaling isoform A. Here attempts are made to demonstrate a relationship between the muscleblind proteins and alternatively spliced insulin receptor by which protein-RNA binding ...

Fuchs corneal endothelial dystrophy is an inherited eye condition, which may cause your cornea to become cloudy.Fuchs dystrophy develops slowly and can affect people to a varying degree. While some people may never have any real problems with their vision, others can require a corneal treatment quite early in life.
The DSEK procedure is most appropriate when there is reduced function of the inner endothelial cell layer - causing corneal edema or swelling (edema).. Normally corneal transparency is dependent on the endothelial cells pumping fluid out of the cornea. If the cornea becomes oedematous, the patients vision worsens. In severe corneal edema, the surface cell layer (epithelium) develops tiny blisters of fluid between the cells (bullous keratopathy). When that happens, the patients vision becomes even worse and the eye can become painful when the blisters rupture.. Corneal endothelial failure is seen in the genetically determined condition of Fuchs corneal endothelial dystrophy, and may also occur following intra-ocular surgery such as cataract extraction.. ...
Background: Altered dosage of the transcription factor PAX6 causes multiple human eye pathophysiologies. PAX6(+/-) heterozygotes suffer from aniridia and aniridia-related keratopathy (ARK), a corneal deterioration that probably involves a limbal epithelial stem cell (LESC) deficiency. Heterozygous Pax6(+/Sey-Neu) (Pax6(+/-)) mice recapitulate the human disease and are a good model of ARK. Corneal pathologies also occur in other mouse Pax6 mutants and in PAX77(Tg/-) transgenics, which over-express Pax6 and model human PAX6 duplication. Methodology/Principal Findings: We used electron microscopy to investigate ocular defects in Pax6(+/-) heterozygotes (low Pax6 levels) and PAX77(Tg/-) transgenics (high Pax6 levels). As well as the well-documented epithelial defects, aberrant Pax6 dosage had profound effects on the corneal stroma and endothelium in both genotypes, including cellular vacuolation, similar to that reported for human macular corneal dystrophy. We used mosaic expression of an X-linked ...

In constrast to bacteria, all archaea possess cell walls lacking peptidoglycan and a number of different cell envelope components have also been described. A paracrystalline protein surface layer, commonly referred to as S-layer, is present in nearly all archaea described to date. S-layers are composed of only one or two proteins and form different lattice structures. In this review, we summarise current understanding of archaeal S-layer proteins, discussing topics such as structure, lattice type distribution among archaeal phyla and glycosylation. The hexagonal lattice type is dominant within the phylum Euryarchaeota, while in the Crenarchaeota this feature is mainly associated with specific orders. S-layers exclusive to the Crenarchaeota have also been described, which are composed of two proteins. Information regarding S-layers in the remaining archaeal phyla is limited, mainly due to organism description through only culture-independent methods. Despite the numerous applied studies using bacterial S
Materials and Methods :. Subjects:. Adult ambulatory patients (18 years of age and older) with a clinical diagnosis of myotonic dystrophy type I were investigated prospectively as part of routine follow-up, from april 2008 to june 2010.

Cellular therapy of the corneal stroma, with either ocular or extraocular stem cells, has been gaining a lot of interest over the last decade. Multiple publications from different research groups are showing its potential benefits in relation to its capacity to improve or alleviate corneal scars, improve corneal transparency in metabolic diseases by enhancing the catabolism of the accumulated molecules, generate new organized collagen within the host stroma, and its immunosuppressive and immunomodulatory properties. Autologous extraocular stem cells do not require a healthy contralateral eye and they do not involve any ophthalmic procedures for their isolation. Mesenchymal stem cells have been the most widely assayed and have the best potential to differentiate into functional adult keratocytes in vivo and in vitro. While embryonic stem cells have been partially abandoned due to ethical implications, the discovery of the induced pluripotent stem cells (iPSC) has opened a new and very promising field for

Difference macular dystrophy macular degeneration - Can you tell me the difference between macular dystrophy and macular degeneration? Macular degeneration. A dystrophy is something a person is born with. A degeneration is an acquired condition that occurs as a person ages. Macular degeneration is a disease of older people, whereby the macula suffers progressive damage and the patient suffers visual loss, either slowly or rapidly. A macular dystrophy usually shows up earlier in life, with variable visual consequences, depending on the disorder.
Stargardt disease is also known as Stargardt macular dystrophy, juvenile macular dystrophy and fundus flavimaculatus. It is an inherited eye condition that affects your macula which is the tiny central part of your retina, the light-sensitive layer at the back of your eye.

The Ophthalmic Genetics and Visual Function Branch (OGVFB) / Ophthalmic Molecular Genetics Section (OMGS) is involved in a number of different approaches to the study inherited diseases affecting the visual system.. One approach to understanding inherited visual diseases uses principles of positional cloning to identify genes important in human Mendelian inherited diseases. Such diseases currently undergoing linkage analysis, gene isolation, or characterization of mutations include retinitis pigmentosa, inherited cataracts, glaucoma, and a number of corneal dystrophies.. A second approach is to attempt to establish associations between DNA sequence changes in or near candidate genes and specific phenotypes. This type of study is most applicable to common diseases with a complex inheritance pattern, and is currently being used for age-related cataracts, primary open angle glaucoma, and high myopia.. Once a candidate gene has been identified and confirmed, the biochemical and pathophysiological ...

Clinical applications of corneal confocal microscopy Mitra Tavakoli1, Parwez Hossain2, Rayaz A Malik11Division of Cardiovascular Medicine, University of Manchester and Manchester Royal Infirmary, Manchester, UK; 2University of Southampton, Southampton Eye Unit, Southampton General Hospital, Southampton, UKAbstract: Corneal confocal microscopy is a novel clinical technique for the study of corneal cellular structure. It provides images which are comparable to in-vitro histochemical techniques delineating corneal epithelium, Bowman’s layer, stroma, Descemet’s membrane and the corneal endothelium. Because, corneal confocal microscopy is a non invasive technique for in vivo imaging of the living cornea it has huge clinical potential to investigate numerous corneal diseases. Thus far it has been used in the detection and management of pathologic and infectious conditions, corneal dystrophies and ecstasies, monitoring contact lens induced corneal changes and for pre and post surgical evaluation
Stargardts disease (also called Stargardts macular degeneration or Stargardts macular dystrophy) is a rare inherited eye condition which affects the central area of the retina called the macula. It is also sometimes called fundus flavimaculatus. It affects about 1 in 10,000 people. Stargardts disease is sometimes called a juvenile macular dystrophy since it tends to first
PK is limited to use in diseases where the benefit of replacing all the disease tissue will provide the best optical or therapeutic results compared with lamellar keratoplasty," he said.. Dr Fourniés talk was followed by a presentation by Dr Vincent Borderie on deep anterior lamellar keratoplasty (DALK).. In a wide-ranging look at the indications and advantages of DALK, Dr Borderie discussed its utility in cases such as keratoconus, infectious keratitis, stromal dystrophies, after corneal trauma and in eyes with failed graft after previous penetrating keratoplasty.. Overall, the technique offers a lot of advantages to modern transplant surgeons, he said. "DALK is associated with higher endothelial cell survival, lower rejection rate, lower glaucoma incidence and higher predicted long-term graft survival. The gold standard is a recipient bend made of Duas layer, Descemets membrane and endothelium. Air injection and intraoperative optical coherence tomography are useful to reach this goal," he ...

  • In our study six previously reported mutations of the TGFBI gene: R124C, R124H, R124L (exon 4), R555W, R555Q, A546T (exon 12) were analyzed using polymerase chain reaction followed by restriction digestion in 114 individuals from 41 unrelated families with different forms of corneal dystrophy. (egms.de)
  • To gain insight into the mechanisms underlying the transforming growth factor-beta induced (TGFBI)-related corneal dystrophies and the influence of the Arg555Trp and Thr538Pro, TGFBI mutations on C-terminal cleavage and cell endoplasmic reticulum (ER) stress were investigated. (nih.gov)
  • Corneal dystrophy-related mutations are more likely to disrupt the interaction of TGFBI with critical binding proteins than affect the whole protein structure. (nih.gov)
  • Fuchs' dystrophy exhibits dominant inheritance, which means that roughly half of an affected person's offspring may inherit it. (cornea.org)
  • Wild-type and mutant TGFBI DNAs were cloned into the pcDNA3.1(-)/myc-his expression vector and overexpressed in HeLa and human corneal epithelial cells (HCE) with transient transfection. (nih.gov)
  • An important gene associated with Corneal Endothelial Dystrophy is SLC4A11 (Solute Carrier Family 4 Member 11), and among its related pathways/superpathways is Glyoxylate metabolism and glycine degradation . (malacards.org)
  • An important gene associated with Corneal Dystrophy, Posterior Polymorphous, 1 is OVOL2 (Ovo Like Zinc Finger 2), and among its related pathways/superpathways are Meiosis and Type I Interferon Signaling Pathways . (malacards.org)
  • Schematic of proposed mechanism of TGFBI-related corneal dystrophies in present study. (nih.gov)
  • The hypothesis of pathogenesis of TGFBI-related corneal dystrophies mainly consists of two aspects: altering the binding interactions of TGFBIp with other critical proteins and interfering with the TGFBIp folding. (nih.gov)
