Identification of photoreceptor genes affected by PRPF31 mutations associated with autosomal dominant retinitis pigmentosa.
Several ubiquitously expressed genes encoding pre-mRNA splicing factors have been associated with autosomal dominant retinitis pigmentosa (adRP), including PRPF31, PRPF3 and PRPF8. Molecular mechanisms by which defects in pre-mRNA splicing factors cause photoreceptor degeneration are not clear. To investigate the role of pre-mRNA splicing in photoreceptor gene expression and function, we have b...
متن کاملNovel PRPF31 mutations associated with Chinese autosomal dominant retinitis pigmentosa patients
PURPOSE To identify the mutations in the pre-mRNA processing factor 31 homolog (PRPF31) gene in Chinese families with autosomal dominant retinitis pigmentosa (adRP) and to characterize the clinical features of those patients who were found to have mutations in the PRPF31 gene. METHODS Detailed ocular examinations were performed, and genomic DNA was isolated by standard methods for genetic dia...
متن کاملGenes and Mutations Causing Autosomal Dominant Retinitis Pigmentosa.
Retinitis pigmentosa (RP) has a prevalence of approximately one in 4000; 25%-30% of these cases are autosomal dominant retinitis pigmentosa (adRP). Like other forms of inherited retinal disease, adRP is exceptionally heterogeneous. Mutations in more than 25 genes are known to cause adRP, more than 1000 mutations have been reported in these genes, clinical findings are highly variable, and there...
متن کاملRhodopsin mutations in autosomal dominant retinitis pigmentosa.
DNA samples from 161 unrelated patients with autosomal dominant retinitis pigmentosa were screened for point mutations in the rhodopsin gene by using the polymerase chain reaction and denaturing gradient gel electrophoresis. Thirty-nine patients were found to carry 1 of 13 different point mutations at 12 amino acid positions. The presence or absence of the mutations correlated with the presence...
متن کاملPRPF4 mutations cause autosomal dominant retinitis pigmentosa.
Retinitis pigmentosa (RP), a disease characterized by progressive loss of photoreceptors, exhibits significant genetic heterogeneity. Several genes associated with U4/U6-U5 triple small nuclear ribonucleoprotein (tri-snRNP) complex of the spliceosome have been implicated in autosomal dominant RP (adRP). HPrp4, encoded by PRPF4, regulates the stability of U4/U6 di-snRNP, which is essential for c...
