Aniridia: A congenital abnormality in which there is only a rudimentary iris. This is due to the failure of the optic cup to grow. Aniridia also occurs in a hereditary form, usually autosomal dominant.Paired Box Transcription Factors: A family of transcription factors that control EMBRYONIC DEVELOPMENT within a variety of cell lineages. They are characterized by a highly conserved paired DNA-binding domain that was first identified in DROSOPHILA segmentation genes.WAGR Syndrome: A contiguous gene syndrome associated with hemizygous deletions of chromosome region 11p13. The condition is marked by the combination of WILMS TUMOR; ANIRIDIA; GENITOURINARY ABNORMALITIES; and INTELLECTUAL DISABILITY.Eye ProteinsHomeodomain Proteins: Proteins encoded by homeobox genes (GENES, HOMEOBOX) that exhibit structural similarity to certain prokaryotic and eukaryotic DNA-binding proteins. Homeodomain proteins are involved in the control of gene expression during morphogenesis and development (GENE EXPRESSION REGULATION, DEVELOPMENTAL).Repressor Proteins: Proteins which maintain the transcriptional quiescence of specific GENES or OPERONS. Classical repressor proteins are DNA-binding proteins that are normally bound to the OPERATOR REGION of an operon, or the ENHANCER SEQUENCES of a gene until a signal occurs that causes their release.Eye Abnormalities: Congenital absence of or defects in structures of the eye; may also be hereditary.Iris: The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.Wilms Tumor: A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.Chromosomes, Human, Pair 11: A specific pair of GROUP C CHROMOSOMES of the human chromosome classification.Pedigree: The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.Anterior Eye Segment: The front third of the eyeball that includes the structures between the front surface of the cornea and the front of the VITREOUS BODY.Urogenital Abnormalities: Congenital structural abnormalities of the UROGENITAL SYSTEM in either the male or the female.Microphthalmos: Congenital or developmental anomaly in which the eyeballs are abnormally small.Aphakia: Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.

Mutational analysis of PAX6: 16 novel mutations including 5 missense mutations with a mild aniridia phenotype. (1/104)

Mutations in the developmental control gene PAX6 have been shown to be the genetic cause of aniridia, which is a severe panocular eye disease characterised by iris hypoplasia. The inheritance is autosomal dominant with high penetrance but variable expressivity. Here we describe a mutational analysis of 27 Danish patients using a dideoxy fingerprinting method, which identified PAX6 mutations in 18 individuals with aniridia. A thorough phenotype description was made for the 18 patients. A total of 19 mutations, of which 16 were novel, are described. Among these were five missense mutations which tended to be associated with a milder aniridia phenotype, and in fact one of them seemed to be non-penetrant. Four of the five missense mutations were located in the paired domain. We also describe a third alternative spliced PAX6 isoform in which two of the four missense mutations would be spliced out. Our observations support the concept of dosage effects of PAX6 mutations as well as presenting evidence for variable expressivity and gonadal mosaicism.  (+info)

Goniosurgery for prevention of aniridic glaucoma. (2/104)

PURPOSE: We conducted a retrospective study to report the long-term success and complications of modified goniosurgery to prevent aniridic glaucoma, an entity that typically is difficult to control medically or surgically. METHODS: Fifty-five eyes in 33 patients who had aniridia without glaucoma and who had goniosurgery were identified. Ninety-one procedures were performed on 55 eyes by 1 surgeon (D.S.W.). Each eye had an average of 1.65 procedures and an average of 200 degrees of goniosurgery. Average patient age at time of initial goniosurgery was 37 months. There were no operative complications. RESULTS: No eye had a decrease in visual acuity at last follow-up. All eyes had a preoperative intraocular pressure (IOP) of less than 21 mm Hg. At last follow-up (average, 9 years 6 months; range, 8 months to 24 years), 49 eyes (89%) had IOP of less than 22 mm Hg without medications. The remaining 6 eyes (11%) had IOP of less than or equal to 22 mm Hg with up to 2 eye drops. Of 224 aniridic eyes of 112 patients that were seen for eye care by 1 of the authors (D.S.W.), 119 eyes (53%) demonstrated glaucoma, as defined by IOP of greater than 21 mm Hg. CONCLUSIONS: Without prophylactic goniotomy, aniridic glaucoma may be expected in half of patients, and when it occurs, it is extremely difficult to control. Prophylactic goniosurgery in selected eyes of young patients with aniridia is effective in preventing aniridic glaucoma.  (+info)

The horse homolog of congenital aniridia conforms to codominant inheritance. (3/104)

Anterior segment dysgenesis syndrome occurs frequently in Rocky Mountain horses and has two distinct ocular phenotypes: (1) large cysts originating from the temporal ciliary body or peripheral retina and (2) multiple anterior segment anomalies including ciliary cysts, iris hypoplasia, iridocorneal adhesions and opacification, nuclear cataract, and megalocornea. To determine if anterior segment dysgenesis syndrome is heritable in horses we performed ophthalmic examinations and collected pedigree information on horses (n = 516) in an extended Rocky Mountain horse pedigree. Logistic regressive segregation analysis of a subset of animals (n = 337) in which the ocular phenotypes of progeny and both parents were known indicated that the codominant inheritance model best fit the data. This model predicted cyst phenotype expression in heterozygous animals and multiple anterior segment anomalies in homozygous animals. Several cases of nonpenetrance of the cyst phenotype were detected in one lineage. The close resemblance between the inheritance and lesions observed in Small eye mice and rats, humans with congenital aniridia or anterior segment malformation, and horses with anterior segment dysgenesis syndrome supported the conclusion that anterior segment dysgenesis syndrome in the horse may be homologous to similar ophthalmic anomalies in other species.  (+info)

3' deletions cause aniridia by preventing PAX6 gene expression. (4/104)

Aniridia is a panocular human eye malformation caused by heterozygous null mutations within PAX6, a paired-box transcription factor, or cytogenetic deletions of chromosome 11p13 that encompass PAX6. Chromosomal rearrangements also have been described that disrupt 11p13 but spare the PAX6 transcription unit in two families with aniridia. These presumably cause a loss of gene expression, by removing positive cis regulatory elements or juxtaposing negative DNA sequences. We report two submicroscopic de novo deletions of 11p13 that cause aniridia but are located >11 kb from the 3' end of PAX6. The clinical manifestations are indistinguishable from cases with chain-terminating mutations in the coding region. Using human x mouse retinoblastoma somatic cell hybrids, we show that PAX6 is transcribed only from the normal allele but not from the deleted chromosome 11 homolog. Our findings suggest that remote 3' regulatory elements are required for initiation of PAX6 expression.  (+info)

Missense mutation at the C-terminus of PAX6 negatively modulates homeodomain function. (5/104)

PAX6 is essential for ocular morphogenesis. Mutations in the PAX6 gene produce various phenotypes, including aniridia, Peters' anomaly, foveal hypoplasia, autosomal dominant keratitis and congenital cataracts. PAX6 functions as a transcription factor and has two DNA binding domains (a paired domain and a homeodomain) which are joined by a linker, and a transactivation domain enriched in proline, serine and threonine (PST) at the C-terminus. The mechanism of PAX6 function is not clearly understood, and few target genes in vertebrates have been identified. We examined disease-causing missense mutations in the PST domain to understand how they affect the function of PAX6. Upon examining the DNA samples of aniridia patients, we identified three missense mutations in the PST domain: P375Q (a novel mutation) and the previously reported Q422R and X423L mutations. On the basis of functional analysis, the P375Q mutant appears to have a normal transactivation activity but lower DNA binding through the paired domain than the wild-type. The Q422R mutation resulted in the loss of DNA binding ability of the PAX6 homeodomain. Substitution analyses of the C-terminal amino acid (codon 422) indicated that an amino acid at codon 422 is required for DNA binding of the homeodomain of intact PAX6 and that the polarity and charge of the side-chain of the terminal amino acid influence this binding.  (+info)

Alveolar capillary dysplasia with misalignment of pulmonary veins and anterior segment dysgenesis of the eye: a report of a new association and review of the literature. (6/104)

The association of alveolar capillary dysplasia with misalignment of pulmonary veins (ACD-MPV) and ocular abnormalities has not been previously reported. We present a case of ACD-MPV and anterior segment dysgenesis of the eye in a full-term infant as well as a review of the relevant literature.  (+info)

Aniridia-associated translocations, DNase hypersensitivity, sequence comparison and transgenic analysis redefine the functional domain of PAX6. (7/104)

The transcription factor PAX6 plays a critical, evolutionarily conserved role in eye, brain and olfactory development. Homozygous loss of PAX6 function affects all expressing tissues and is neonatally lethal; heterozygous null mutations cause aniridia in humans and the Small eye (Sey) phenotype in mice. Several upstream and intragenic PAX6 control elements have been defined, generally through transgenesis. However, aniridia cases with chromosomal rearrangements far downstream of an intact PAX6 gene suggested a requirement for additional cis-acting control for correct gene expression. The likely location of such elements is pinpointed through YAC transgenic studies. A 420 kb yeast artificial chromosome (YAC) clone, extending well beyond the most distant patient breakpoint, was previously shown to rescue homozygous Small eye lethality and correct the heterozygous eye phenotype. We now show that a 310 kb YAC clone, terminating just 5' of the breakpoint, fails to influence the Sey phenotypes. Using evolutionary sequence comparison, DNaseI hypersensitivity analysis and transgenic reporter studies, we have identified a region, >150 kb distal to the major PAX6 promoter P1, containing regulatory elements. Components of this downstream regulatory region drive reporter expression in distinct partial PAX6 patterns, indicating that the functional PAX6 gene domain extends far beyond the transcription unit.  (+info)

PAX6 mutation as a genetic factor common to aniridia and glucose intolerance. (8/104)

A paired homeodomain transcription factor, PAX6, is a well-known regulator of eye development, and its heterozygous mutations in humans cause congenital eye anomalies such as aniridia. Because it was recently shown that PAX6 also plays an indispensable role in islet cell development, a PAX6 gene mutation in humans may lead to a defect of the endocrine pancreas. Whereas heterozygous mutations in islet-cell transcription factors such as IPF1/IDX-1/STF-1/PDX-1 and NEUROD1/BETA2 serve as a genetic cause of diabetes or glucose intolerance, we investigated the possibility of PAX6 gene mutations being a genetic factor common to aniridia and diabetes. In five aniridia and one Peters' anomaly patients, all of the coding exons and their flanking exon-intron junctions of the PAX6 gene were surveyed for mutations. The results of direct DNA sequencing revealed three different mutations in four aniridia patients: one previously reported type of mutation and two unreported types. In agreement with polypeptide truncation and a lack of the carboxyl-terminal transactivation domain in all of the mutated PAX6 proteins, no transcriptional activity was found in the reporter gene analyses. Oral glucose tolerance tests revealed that all of the patients with a PAX6 gene mutation had glucose intolerance characterized by impaired insulin secretion. Although we did not detect a mutation within the characterized portion of the PAX6 gene in one of the five aniridia patients, diabetes was cosegregated with aniridia in her family, and a single nucleotide polymorphism in intron 9 of the PAX6 gene was correlated with the disorders, suggesting that a mutation, possibly located in an uncharacterized portion of the PAX6 gene, can explain both diabetes and aniridia in this family. In contrast, the patient with Peters' anomaly, for which a PAX6 gene mutation is a relatively rare cause, showed normal glucose tolerance (NGT) and did not show a Pax6 gene mutation. Taken together, our present observations suggest that heterozygous mutations in the PAX6 gene can induce eye anomaly and glucose intolerance in individuals harboring these mutations.  (+info)

Purpose: : PAX6 is a phylogenetically conserved transcription factor almost universally employed to direct eye development that regulates the tissue-specific expression of diverse molecules, including transcription factors, cell adhesion molecules, hormones, and structural proteins. Its mutations, frequently point mutations that generate the introduction of a premature stop codon, lead to a variety of hereditary ocular malformations being the most common congenital aniridia (AN2; OMIM 106210). However, not all aniridia cases can be explained by mutations in the PAX6 gene, but gross deletion can be detected by MLPA. In this study we perform the first MLPA analisys in mexican individuals with congenital aniridia. Methods: : An affected family underwent full ophthalmologic examination including visual acuity, slit lamp inspection, intraocular pressure. Blood samples were drawn by venipuncture, and genomic DNA was extracted, PCR amplification of the complete coding region of the PAX6 gene (14 ...

She was managed conservatively. Various modalities of treatment are reviewed.Keywords: aniridia, sporadic, nystagmus, cataract, glaucoma, keratopathy, tattooing, syndrome, fovea hypoplasia and optic disc hypoplasia
A 2 year old female presenting with bilateral sporadic aniridia was found to have an apparently balanced reciprocal translocation with a chromosome 11 breakpoint within band p13. Fluorescence in situ hybridisation (FISH) studies with distal 11p13 specific cosmids showed that the chromosome 11 breakpoint lay between the aniridia (PAX6) locus and a region approximately 100 kb distal to PAX6 defined by the cosmid FO2121. Although this patient did not have a detectable deletion within PAX6, her aniridia may have resulted from a disruption of the distal chromatin domain containing either enhancers or regulators for PAX6. This case may therefore be another example of aniridia caused by a position effect as recently described in two familial aniridia patients in which the phenotype cosegregated with chromosome abnormalities with 11p13 breakpoints.. ...
PURPOSE: The PAX6 gene mutation in aniridia has been studied in various ethnic patients, but not well studied in the Chinese population. In the present study, we have investigated the PAX6 gene mutation in a Chinese family with congenital aniridia.. METHODS: Total genomic DNA was isolated from peripheral blood of three aniridia patients (who also suffered from bilateral congenital cataracts) and two non-carriers in a Chinese family. Fourteen exons of the PAX6 gene were amplified by polymerase chain reaction (PCR). PCR products of each exon were analyzed by single strand conformational polymorphism (SSCP). The PCR products with abnormal SSCP patterns were subcloned and sequenced to identify the mutation.. RESULTS: Abnormal SSCP patterns were found in all affected patients but not in non-carrier family members. A novel mutation (c.857delG) in exon 7 was detected by sequencing analysis. This frame shift mutation was predicted to lead to a pre-stop codon in exon 8, and generate a novel 40 amino acid ...
NIH Rare Diseases : 50 aniridia is an eye disorder characterized by a complete or partial absence of the colored part of the eye (the iris) and is usually associated with foveal hypoplasia (underdevelopment of the part of the eye responsible for sharp central vision). this combination can lead to decreased visual acuity and involuntary eye movements (nystagmus) in affected infants. people with aniridia may also have other eye problems including increased pressure in the eye (glaucoma), clouding of the lens of the eye (cataracts), and abnormalities of the cornea. many of these eye problems contribute to progressive vision loss in affected individuals. occasionally, people with aniridia have behavioral problems, developmental delay, and problems detecting odors. aniridia may occur either as an isolated eye abnormality or as part of the wilms tumor-aniridia-genital anomalies-retardation (wagr) syndrome. isolated aniridia may be caused by mutations in the pax6 gene and is inherited in an autosomal ...
Aniridia means the iris, which is the coloured part of your eye, is missing or incomplete. Some children with aniridia may only have mild blurred vision and others may have quite a lot of sight loss.What is aniridia?Aniridia is a rare condition which means the iris, the coloured part of your eye, is missing or incomplete. Aniridia normally affects both eyes and it is a condition which babies are born with.
The family tree is shown in Figure 1A. Case I-1 is a 52 year old man with visual impairment and nystagmus. He had cataract from an early age (the detail was unknown). His vision was right eye finger counting at 20 cm and left eye 0.01; eye examination revealed bilateral partial aniridia, dense cataract, corneal pannus, and foveal hypoplasia (Fig2A, B). His cataracts were removed and posterior chamber intraocular lenses were implanted at age 52. One son, II-1, is 16 years old with nystagmus, visual acuities of right eye 0.3 and left eye 0.2, bilateral corneal pannus, iris thinning, and mild foveal hypoplasia; his lenses were clear (Fig 2 C, D). Another son, II-2, is 14 years old with nystagmus, visual acuities of right eye 0.2 and left eye 0.2, bilateral iris thinning, corneal pannus, and mild foveal hypoplasia; his lenses were clear (Fig 2 E, F). Case II-3 is a 13 year old male with nystagmus, visual acuities of right eye 0.3 and left eye 0.2, corneal pannus, partial aniridia, zonular cataracts, ...
Purpose : Aniridia is a rare autosomal dominant disorder caused by mutations in PAX6 (Paired Box 6). Although named for lack of iris, aniridia is a panocular disorder, with vision loss attributable to three main causes: 1) hypomorphic fovea, 2) progressive corneal clouding, and 3) progressive glaucoma. Current treatments may delay vision loss, but do not prevent the blindness experienced by most people with aniridia. Gene therapy is a promising treatment strategy that may delay, or even prevent, vision loss. Here we focus on gene therapy for the corneal pathology. Methods : EmGFP (emerald GFP), PAX6, 3xFLAG/PAX6, and PAX6/3xFLAG mRNAs were injected into Xenopus laevis embryos, which were fixed and examined 14 days later. Additionally, EmGFP and 3xFLAG/PAX6 constructs, driven by smCBA (ubiquitous) or a human MiniPromoter (targeted to the cornea) were cloned into a custom rAAV genome, and packaged into rAAV9 at the University of Pennsylvania Vector Core. Viruses were introduced into wild-type and ...
The AN2 region of the short arm of chromosome 11 (11p13) includes the PAX6 gene (named for its PAired boX status), whose gene product helps regulate a cascade of other genetic processes involved in the development of the eye (as well as other nonocular structures). This PAX6 gene is around 95% similar to the pax gene found in zebrafish, a creature whose ancestors diverged from human evolutionary development around 400 million years ago. Thus the PAX6 gene is highly conserved across evolutionary lineages.. Defects in the PAX6 gene cause aniridia-like ocular defects in mice (as well as Drosophila). Aniridia is a heterozygous disorder, meaning that only one of the two chromosome 11 copies is affected. When both copies are altered (homozygous condition), the result is a uniformly fatal condition with near complete failure of entire eye formation. In 2001, two cases of homozygous aniridia patients were reported; the fetuses died prior to birth and had severe brain damage. In mice, homozygous small ...
Surgical Treatment Cataracts are extracted in aniridic patients if they produce a significant decrease in visual acuity in addition to the visual loss inherent to aniridia proper. In many patients with cataract even with extensive lens opacities the visual acuity is 42 D. Brémond-Gignac relatively preserved and compatible with the foveal hypoplasia. Cataract surgery is best deferred in these patients because of low potential for visual improvement and increased risks of complications as glaucoma or corneal dystrophy.

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 ...
Aniridia is an eye disorder characterized by a complete or partial absence of the colored part of the eye (the iris). These iris abnormalities may cause the pupils to be abnormal or misshapen. Aniridia can cause reduction in the sharpness of vision (visual acuity) and increased sensitivity to light (photophobia).People with aniridia can also have other eye problems. Increased pressure in the eye (glaucoma) typically appears in late childhood or early adolescence. Clouding of the lens of the eye (cataracts), occur in 50 percent to 85 percent of people with aniridia. In about 10 percent of affected people, the structures that carry information from the eyes to the brain (optic nerves) are underdeveloped. Individuals with aniridia may also have involuntary eye movements (nystagmus) or underdevelopment of the region at the back of the eye responsible for sharp central vision (foveal hypoplasia). Many of these eye problems contribute to progressive vision loss in affected individuals. The severity of ...
Aniridia is a congenital, hereditary, bilateral, extreme form of iris hypoplasia that may be associated with other ocular defects. It describes an extreme form of iris hypoplasia in which the iris appears absent on superficial clinical examination.
Nonsense mutations leading to premature stop codons are common occurring in approximately 12% of all human genetic diseases. Thus, pharmacological nonsense mutation suppression strategies would be beneficial to a large number of patients if the drugs could be targeted to the affected tissues at the appropriate time. Here, we used nonsense suppression to manipulate Pax6 dosage at different developmental times in the eye of the small eye (Pax6(Sey/+); G194X) mouse model of aniridia. Efficacy was assessed by functional assays for visual capacity, including electroretinography and optokinetic tracking (OKT), in addition to histological and biochemical studies ...

At the beginning of this segment, Dr. Strong explains that she became a part time faculty member and had her children after her post-doctoral study. She realized, however, that she "would go nowhere" on part time status and joined the full time faculty with a position in the Medical Genetics Center in 1976. She then describes how she focused her research interests on childhood cancer and genetic epidemiology: she would look at individuals who had had retinoblastoma as tiny babies, who had been irradiated as part of therapy, and who had additional cancers, working with the assumption that this risk came from genetic predisposition. She explains two hypotheses that did not yield results, then explains how she discovered that aniridia (the absence of an iris in the eye) and Wilms tumor (of the kidney) are controlled by contiguous genes. She could now go to patients, she explains, and give them information about their risks for developing Wilms tumor or passing the predisposition to the next ...
Aniridia is an eye condition that effects the development of the eye in children. Typically it stops the eye developing before it is mature.

We did get a surprising call yesterday. It was from our pharmacy. (We really love our pharmacy). They called to chat with me about Pipers future medications. They also wanted us to know that they keep a prayer box, and they will be praying for our family as we go through surgery and recovery. Isnt that awesome?!? I never imagined receiving such personal and caring service from a pharmacy! God has really placed us with some amazing people. Recently our pediatrician wanted to pray with us as well. Its comforting to know that were being covered with Gods love and provision ...
Piper did not have a great night. The nurses come in every 4 hours to check her vitals. The nurse last night did not know how to do it without waking her up each time! She opened the blinds to let the hall light in... and when Piper stirred, the nurse would TALK to her! You never TALK to a baby or make eye contact with them if you want them to go back to sleep! I know she didnt do it intentionally, but that did not make for a good night! The other nurses do a fabulous job, and they never wake her up. They can draw blood for labs, check her vitals and even change her diaper without ever waking her! Theyre good!!! ... Irony?!?! ... Their best nurse is a man, and I am fairly certain he does not have any children of his own. He really loves these kids at Duke, though!. The nurse came in a while ago holding Pipers lab report. ANC = 36. Her other counts are going up, though. Her platelet level is back to an acceptable level, and her WBC count is getting better too. I doubt they will let us go home ...

AU - Young, S. Robert. AU - Favor, Jack. AU - Maas, Richard L.. PY - 1994/8. Y1 - 1994/8. N2 - The human eye malformation aniridia results from haploinsufficiency of PAX6, a paired box DNA-binding protein. To study this dosage effect, we characterized two PAX6 mutations in a family segregating aniridia and a milder syndrome consisting of congenital cataracts and late onset corneal dystrophy. The nonsense mutations, at codons 103 and 353, truncate PAX6 within the N-terminal paired and C-terminal PST domains, respectively. The wild-type PST domain activates transcription autonomously and the mutant form has partial activity. A compound heterozygote had severe craniofacial and central nervous system defects and no eyes. The pattern of malformations is similar to that in homozygous Sey mice and suggests ...

Aniridia is a rare condition whose presence should alert clinicians to the possibility of other abnormalities. One of the differential diagnoses that should be considered is Gillespie syndrome, in which aniridia is associated with cerebellar ataxia and mental retardation. There are only 21 reported cases of Gillespie syndrome. The goal of this paper is to describe the clinical manifestations of a girl born to a consanguineous couple who presented with typical findings of the Gillespie syndrome, in addition to previously undescribed alterations of her distal extremities ...

Screening tests are done in children with an increased risk of Wilms tumor. These tests may help find cancer early and decrease the chance of dying from cancer.. In general, children with an increased risk of Wilms tumor should be screened for Wilms tumor every three months until they are at least 8 years old. An ultrasound test of the abdomen is usually used for screening. Small Wilms tumors may be found and removed before symptoms occur. Children with Beckwith-Wiedemann syndrome or hemihyperplasia are also screened for liver and adrenal tumors that are linked to these genetic syndromes. A test to check the alpha-fetoprotein (AFP) level in the blood and an ultrasound of the abdomen are done until the child is 4 years old. An ultrasound of the kidneys is done after the child is 4 years old. In children with certain gene changes, a different schedule for ultrasound of the abdomen may be used..

A paper detailing the breakthrough appears in the high-impact journal Transplantation this week.. The trial was conducted on three patients; two with extensive corneal damage resulting from multiple surgeries to remove ocular melanomas, and one with the genetic eye condition aniridia. Other causes of cornea damage can include chemical or thermal burns, bacterial infection and chemotherapy.. "The procedure is totally simple and cheap," said lead author of the study, UNSWs Dr Nick Di Girolamo. "Unlike other techniques, it requires no foreign human or animal products, only the patients own serum, and is completely non-invasive.. "Theres no suturing, there is no major operation: all thats involved is harvesting a minute amount - less than a millimeter - of tissue from the ocular surface," Dr Di Girolamo said.. "If youre going to be treating these sorts of diseases in third world countries all you need is the surgeon and a lab for cell culture. You dont need any fancy equipment.". Because the ...

Bilateral and multifocal Wilms tumors may have a genetic predisposition. At least 10 genes have been associated with Wilms tumor. WT1 gene is located on the short arm of chromosome 11 (11p13). WT1 encodes a zinc finger transcription factor that is critical to normal development of the kidneys and gonads but also acts as a tumor suppressor. The WT1 protein likely affects cell growth, differentiation, and/or apoptosis. Germline mutations in WT1 have been found in about 2% of phenotypically normal children with Wilms tumor. Germline WT1 mutations in children with Wilms tumor does not necessarily confer a poor prognosis. The offspring of those with germline mutation in WT1 may also be at increased risk of developing Wilms tumor. WT1 mutation is more common in those children with Wilms tumor and one of the following: WAGR syndrome, Denys-Drash syndrome, or sporadic aniridia. Genitourinary anomalies, including hypospadias and cryptorchidism. Bilateral Wilms tumor. Unilateral Wilms tumor with ...
WAGR syndrome is a disorder that affects many body systems and is named for its main features: Wilms tumor, anirida, genitourinary anomalies, and intellectual disability (formerly referred to as mental retardation).. People with WAGR syndrome have a 45 to 60 percent chance of developing Wilms tumor, a rare form of kidney cancer. This type of cancer is most often diagnosed in children but is sometimes seen in adults.. Most people with WAGR syndrome have aniridia, an absence of the colored part of the eye (the iris). This can cause reduction in the sharpness of vision (visual acuity) and increased sensitivity to light (photophobia). Aniridia is typically the first noticeable sign of WAGR syndrome. Other eye problems may also develop, such as clouding of the lens of the eyes (cataracts), increased pressure in the eyes (glaucoma), and involuntary eye movements (nystagmus).. Abnormalities of the genitalia and urinary tract (genitourinary anomalies) are seen more frequently in males with WAGR syndrome ...

Every year I look forward to WAGR weekend. It is a place where everyone is the same and you dont get looked at funny when your brother is screaming or going through another meltdown. When you are at WAGR Weekend you dont have to feel alone, because you are not the only family that is going through the meltdowns, temper and anger problems. WAGR weekend is a time when you can connect with other siblings that share and endure the same things as you. This year I was very lucky to spend time with Rockie. I loved that we could have fun together and share stories about our siblings. WAGR Weekend is a great way for families to connect with one another and to feel at home. I am very excited that my family is hosting WAGR Weekend again in 2011 and I hope to see everyone there!. Ashley Prusakiewicz, MI (sister to Nicholas, 14 years old). Reprinted from the WINGS newsletter, Fall/Winter 2010. ...
My husband John and I with our daughter Ashley attended our first WAGR weekend in July of 2010. During a deployment, John had found a web site about 11p- deletion, which our daughter Ashley was diagnosed with in 1988. He forwarded this information on to me and I quickly looked into it.. At the time of Ashleys diagnosis the doctor said that her chromosome deletion was rare with about 1 in 100,000 live births. She gave us some information and sent us on our way with numerous follow up appointments and referrals. As first time parents of a precious four month old, this type of news is devastating. There were no groups to support families; there were no support services for this diagnosis. I was very glad we had finally found a support group and that we were no longer alone.. Before attending this weekend, I had not met another child with the same diagnosis as Ashley.. What a great time we had at our first WAGR Weekend event. I had found a few people within this group on the internet and talked and ...

Objective: The objective of this study is to identify genetic causes of inherited eye conditions through whole exome or whole genome sequencing. This includes identifying mutations in known genes or novel genes for recognized conditions, as well as identifying mutations in novel genes for previously uncharacterized genetic conditions involving the eye.. Study Population: We plan to recruit 310 participants, to include both probands with an eye condition under study and unaffected family members. Ideally unaffected family members will be parents of a proband.. Design: Participants will be recruited through other pre-existing NIH protocols, such as the NEI Evaluation and Treatment protocol (08-EI-0169), the NEI Screening protocol (08-EI-0102), and the Genetics of Uveal Coloboma protocol (13-EI-0049). Self-referred patients or patients referred by an outside clinician will be screened for eligibility under a pre-existing NIH protocol. Phenotyped patients eligible for participation and their ...

Congenital nystagmus onset is typically between 6 weeks and several months of age. If it starts after 6 months of age, this is considered acquired and may require imaging studies. Infantile nystagmus tends to be divided into two groups, depending on the underlying problem. One group arises from an abnormal afferent (or sensory) system, and the other from an abnormal efferent (motor) system. The efferent type is more common, but sometimes patients have early nystagmus due to afferent, or vision system, problems. In patients with early nystagmus secondary to afferent problems, conditions that limit their vision are thought to be responsible for the development of their nystagmus. The brain needs feedback from the eyes, through vision, to learn to keep them steady. Conditions that can be associated with this type of nystagmus include congenital cataracts, optic nerve hypoplasia, Lebers congenital amaurosis, achromatopsia, oculocutaneous albinism, aniridia, choroidal coloboma, severe refractive ...
