Analysis of RP2 and RPGR Mutations in Five X-Linked Chinese Families with Retinitis Pigmentosa
Mutations in RP2 and RPGR genes are responsible for the X-linked retinitis pigmentosa (XLRP). In this study, we analyzed the RP2 and RPGR gene mutations in five Han Chinese families with XLRP. An approximately 17Kb large deletion including the exon 4 and exon 5 of RP2 gene was found in an XLRP family. In addition, four frameshift mutations including three novel mutations of c.1059 + 1 G > T, c....
متن کاملMutational screening of the RP2 and RPGR genes in Spanish families with X-linked retinitis pigmentosa.
PURPOSE The X-linked form of retinitis pigmentosa (XLRP) is the most severe type because of its early onset and rapid progression. Five XLRP loci have been mapped, although only two genes, RPGR (for RP3) and RP2, have been cloned. In this study, 30 unrelated XLRP Spanish families were screened to determine the molecular cause of the disease. METHODS Haplotype analysis was performed, to determ...
متن کاملDisease course of patients with X-linked retinitis pigmentosa due to RPGR gene mutations.
PURPOSE To measure the rates of visual acuity, visual field, and ERG loss in patients with X-linked retinitis pigmentosa due to RPGR mutations and to determine whether these rates differ from those of patients with dominant retinitis pigmentosa due to RHO mutations. METHODS Snellen visual acuities, Goldmann visual field areas (V4e white test light), and 30 Hz (cone) full-field ERG amplitudes ...
متن کاملX-linked retinitis pigmentosa: mutation spectrum of the RPGR and RP2 genes and correlation with visual function.
PURPOSE To assess the frequency of RPGR and RP2 mutations in a set of 85 patients with X-linked retinitis pigmentosa (XLRP) and to compare the visual function of patients with mutations in RPGR versus RP2. METHODS Eighty-five unrelated patients with XLRP were ascertained, mainly from North America. The single-strand conformation polymorphism (SSCP) and a direct sequencing technique were used ...
متن کاملA comprehensive mutation analysis of RP2 and RPGR in a North American cohort of families with X-linked retinitis pigmentosa.
X-linked retinitis pigmentosa (XLRP) is a clinically and genetically heterogeneous degenerative disease of the retina. At least five loci have been mapped for XLRP; of these, RP2 and RP3 account for 10%-20% and 70%-90% of genetically identifiable disease, respectively. However, mutations in the respective genes, RP2 and RPGR, were detected in only 10% and 20% of families with XLRP. Mutations in...
