Genetic heterogeneity in Rieger eye malformation.
نویسندگان
چکیده
A three generation family with Rieger eye malformation sequence is described. No other abnormalities were present apart from the eye malformation. Linkage to EGF and D4S193 localised in 4q25 was excluded and this indicates that Rieger eye malformation is genetically different from typical Rieger syndrome with teeth and umbilical anomalies.

Multiple congenital anomalies including the Rieger eye malformation in a boy with interstitial deletion of (4) (q25-->q27) secondary to a balanced insertion in his normal father: evidence for haplotype insufficiency causing the Rieger malformation.
A 7 year old boy with minor facial anomalies, the Rieger eye malformation, reduced vision, genital anomalies, and severe mental retardation had deletion of the segment 4q24-->q26. His phenotypically normal father had a balanced insertion of that segment into the distal long arm of chromosome 6: 46,XY,ins(6;4)(q26;q24q26). Microsatellite loci flanking the RIEG gene on 4q25 were deleted giving in...
متن کاملRieger syndrome: case report.
Rieger syndrome is a dysembryogenetic disease in which labyrinthic damage can be associated with other genetic anomalies. The case presented here is of a patient who has bilateral dysgenesis of the iris, with bulbar atrophy and dyscoria. The patient does not present any malformation of the craniofacial structures, of the periumbilical skin, or of the skeletal bones. The case is, therefore, a va...
متن کاملAxenfeld-Rieger Syndrome Associated with Congenital Glaucoma and Cytochrome P4501B1 Gene Mutations
Developmental anomalies of the ocular anterior chamber angle may lead to an incomplete development of the structures that form the conventional aqueous outflow pathway. Thus, disorders that present with such dysfunction tend to be associated with glaucoma. Among them, Axenfeld-Rieger (ARS) malformation is a rare clinical entity with an estimated prevalence of one in every 200,000 individuals. T...

PURPOSE To determine the possible molecular genetic defect underlying Axenfeld-Rieger anomaly (ARA) and to identify the pathogenic mutation causing this anterior segment dysgenesis in an Indian pedigree. METHODS The FOXC1 gene was amplified from genomic DNA of members of an ARA-affected family and control subjects using four novel sets of primers. The amplicons were directly sequenced, and th...

PURPOSE To unravel the molecular genetic background in families with congenital cataract in association with microcornea (CCMC, OMIM 116150). METHODS CCMC families were recruited from a national database on hereditary eye diseases; DNA was procured from a national gene bank on hereditary eye diseases and by blood sampling from one large family. Genomewide linkage analysis, fine mapping, and d...
