The genetic profile of Leber congenital amaurosis in an Australian cohort
BACKGROUND Leber congenital amaurosis (LCA) is a severe visual impairment responsible for infantile blindness, representing ~5% of all inherited retinal dystrophies. LCA encompasses a group of heterogeneous disorders, with 24 genes currently implicated in pathogenesis. Such clinical and genetic heterogeneity poses great challenges for treatment, with personalized therapies anticipated to be the...

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...
متن کاملMolecular 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 کاملGenetic ablation of Pals1 in retinal progenitor cells models the retinal pathology of Leber congenital amaurosis.
Mutation of the polarity gene Crumbs homolog 1 (CRB1) is responsible for >10% of Leber congenital amaurosis (LCA) cases worldwide; LCA is characterized by early-onset degenerative retinal dystrophy. The role of CRB1 in LCA8 pathogenesis remains elusive since Crb1 mouse mutants, including a null allele, have failed to mimic the early-onset of LCA, most likely due to functional compensation by cl...
