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.

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
The term corneal dystrophy embraces a heterogenous group of bilateral genetically determined non-inflammatory corneal diseases that are restricted to the cornea. The designation is imprecise but remains in vogue because of its clinical value. Clinically, the corneal dystrophies can be divided into three groups based on the sole or predominant anatomical location of the abnormalities. Some affect primarily the corneal epithelium and its basement membrane or Bowman layer and the superficial corneal stroma (anterior corneal dystrophies), the corneal stroma (stromal corneal dystrophies), or Descemet membrane and the corneal endothelium (posterior corneal dystrophies). Most corneal dystrophies have no systemic manifestations and present with variable shaped corneal opacities in a clear or cloudy cornea and they affect visual acuity to different degrees. Corneal dystrophies may have a simple autosomal dominant, autosomal recessive or X-linked recessive Mendelian mode of inheritance. Different corneal
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 ...

An important gene associated with Corneal Dystrophy, Thiel-Behnke Type is TGFBI (Transforming Growth Factor Beta Induced). Affiliated tissues include eye, and related phenotypes are Increased cilium length after serum starvation and vision/eye ...
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 ...

Purpose : Transforming growth factor-β (TGF-β)-induced gene (TGFBI) protein (TGFBIp) is associated with a granular corneal dystrophy type 2 (GCD2), and plays a role in tumorigenesis. Dosage of TGFBI can affect disease phenotypes of this disease, but the underlying molecular mechanisms have not been fully elucidated. We investigate here the contributions of microRNA (miRNA) and TGF-β to TGFBI expression in corneal fibroblasts. Methods : Isolation, immortalization, and culture of primary corneal fibroblast were performed. RNA Isolation and Quantitative real-time PCR were done. Levels of miRNAs were normalized to RNU6B. Relative quantification was analyzed by the system software analysis based on 2−ΔΔCt method. The precursor miR-9, miR-21, miR-181a, miR-181a-3p, miR-181a-2-3p and negative miR precursor were transfected at a final concentration of 100 nM with G-Fectin and Lipofectamine™ 2000 reagent (Invitrogen Life Technologies). Western blotting was done with got anti-TGFBIp (R&D Systems, ...
Gelsolin is an actin-severing protein that attains an open functional conformation in the presence of Ca or low pH. Mutations (D187N/Y) in the second domain of gelsolin trigger the proteolytic pathway producing amyloidogenic fragments that form the pathological hallmark of gelsolin amyloidosis and lattice corneal dystrophy type 2 (LCD2). Here, we show that the D187N mutant gelsolin in a Ca depleted, low pH-activated, open conformation could assemble into amyloidogenic oligomers without necessarily undergoing the specific proteolytic step. Although both wild-type (WT) and mutant proteins exhibit closely overlapping globular shapes at physiological conditions, the latter exhibits subjugated actin depolymerization, loss of thermodynamic stability, and folding cooperativity. Mutant gelsolin displayed aberrant conformational unwinding and formed structural conformers with high associative properties at low pH conditions. A SAXS intensity profile and Guinier analysis of these conformers showed the ...
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 ...
MENLO PARK, Calif., May 6, 2016 /CNW/ -- Avellino Labs Commences Cross-Sectional Study of the Prevalence of TGFBI Corneal Dystrophies in a North American Population.
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 ...

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. Links to sites about this disease:. ...
Flecks consisting of brilliant reflective blue dots and streaks were a prominent biomicroscopical feature in three patients with Cogans microcystic corneal dystrophy. Two patients required epithelial debridement. We used the material obtained to investigate their histology and ultrastructure. A subepithelial accumulation of basement membrane-like material composed of ultrastructurally fine granules was deposited in alternating layers of compaction and rarefaction. The layers lie mostly parallel to the anterior corneal surface, but in some places they are folded. Such foldings are possibly the sites of multilaminar reflection and constructive interference, giving rise to the blue iridescence. ...

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. ...

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.

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 ...
Avellino Titanium Magnetic Bracelet combines the benefits of four bio elements of germanium, far infra red fir, negative ions and magnets therapy into one bracelet.
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 ...

Sulfotransferase that utilizes 3-phospho-5-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of non-reducing N-acetylglucosamine (GlcNAc) residues and O-linked sugars of mucin-type acceptors. Acts on the non-reducing terminal GlcNAc of short carbohydrate substrates. However, it does not transfer sulfate to longer carbohydrate substrates that have poly-N-acetyllactosamine structures. Has no activity toward keratan. Not involved in generating HEV-expressed ligands for SELL. Its substrate specificity may be influenced by its subcellular location ...
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 ...
