Molecular genetics of Leber congenital amaurosis.
Leber congenital amaurosis (LCA) is the most common inherited cause of blindness in childhood and is characterised by a severe retinal dystrophy before the age of one year. Six genes have been identified that together account for approximately half of all LCA patients. These genes are expressed preferentially in the retina or the retinal pigment epithelium. Their putative functions are quite di...

متن کاملCRB1-Related Leber Congenital Amaurosis: Reporting Novel Pathogenic Variants and a Brief Review on Mutations Spectrum
Background: Leber congenital amaurosis (LCA) is a rare inherited retinal disease causing severe visual impairment in infancy. It has been reported that 9-15% of LCA cases have mutations in CRB1 gene. The complex of CRB1 protein with other associated proteins affects the determination of cell polarity, orientation, and morphogenesis of photoreceptors. Here, we report three novel pathogenic varia...
متن کاملMolecular characterization of Leber congenital amaurosis in Koreans
PURPOSE Leber congenital amaurosis (LCA) is the most severe form of inherited retinal dystrophy, and invariably leads to blindness. LCA is a genetically and clinically heterogenous disorder. Although more than nine genes have been found to be associated with LCA, they only account for about half of LCA cases. We performed a comprehensive mutational analysis on nine known genes in 20 unrelated p...
متن کاملDisc oedema in congenital amaurosis of Leber.
Since it was first described by Theodor Leber as 'pigmentary retinitis with congenital amaurosis' (Leber, I867), the entity which bears his name has been the subject of sporadic reports defining its clinical and pathological characteristics. It accounted for about io per cent of the blindness in Sweden (Alstrom and Olsen, 1957) and i8 per cent among children in a series in Holland (SchappertKim...
