چکیده

PURPOSE To catalog mutations that underlie retinitis pigmentosa (RP) in Saudi Arabia using a representative sample. METHODS Fifty-two patients with RP were recruited and their homozygosity mapping, with or without linkage analysis, was used to suggest the causative genes followed by bidirectional sequencing. RESULTS Mutations were identified in 94% of our study cohort, including seven that were novel. CONCLUSIONS Homozygosity mapping is an extremely robust approach in the study of retinitis pigmentosa in the setting of high rates of consanguinity. BBS3 mutations can rarely present as nonsyndromic RP.

Simultaneous Presence of Macular Corneal Dystrophy and Retinitis Pigmentosa in Three Members of a Family

Macular corneal dystrophy (MCD) is an autosomal recessive hereditary disease. In most cases, various mutations in carbohydrate sulfotransferase 6 (CHST6) gene are the main cause of MCD. These mutations lead to a defect in keratan sulfate synthesis. Retinitis pigmentosa (RP) is another eye disorder with nyctalopia as its common symptom. It has been shown that more than 65 genes have been implica...
