coloboma/cysteine

Ocular coloboma is a common eye malformation resulting from incomplete fusion of the optic fissure during development. Coloboma is often associated with microphthalmia and/or contralateral anophthalmia. Coloboma shows extensive locus heterogeneity associated with causative mutations identified in

BACKGROUND Renal coloboma syndrome (RCS) is a highly variable syndrome characterized by renal and ocular abnormalities. It is associated in about 50 % of cases with mutations of PAX2, a gene encoding a transcription factor required during development. METHODS The case study involves two monozygotic

OBJECTIVE To describe a new phenotype with an arginine-to-cysteine mutation at position 116 (Arg116Cys) in the CRYAA gene. METHODS We investigated a 4-generation French family with autosomal dominant cataract and performed a genetic linkage analysis using microsatellite DNA markers encompassing 15

Microphthalmia, coloboma and cataract are part of a spectrum of developmental eye disorders in humans affecting ~ 12 per 100 000 live births. Currently, variants in over 100 genes are known to underlie these conditions. However, at least 40% of affected individuals remain without a clinical genetic

Colobomatous macrophthalmia with microcornea syndrome (MACOM, Online Mendelian Inheritance in Man (OMIM) 602499) is an autosomal dominantly inherited malformation of the eye, which is characterized by microcornea with increased axial length, coloboma of the iris and of the optic disc, and severe
