Hypomorphic mutations in TRNT1 cause retinitis pigmentosa with erythrocytic microcytosis.
Retinitis pigmentosa (RP) is a highly heterogeneous group of disorders characterized by degeneration of the retinal photoreceptor cells and progressive loss of vision. While hundreds of mutations in more than 100 genes have been reported to cause RP, discovering the causative mutations in many patients remains a significant challenge. Exome sequencing in an individual affected with non-syndromi...
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...
متن کاملSPP2 Mutations Cause Autosomal Dominant Retinitis Pigmentosa
Retinitis pigmentosa (RP) shows progressive loss of photoreceptors involved with heterogeneous genetic background. Here, by exome sequencing and linkage analysis on a Chinese family with autosomal dominant RP, we identified a putative pathogenic variant, p.Gly97Arg, in the gene SPP2, of which expression was detected in multiple tissues including retina. The p.Gly97Arg was absent in 800 ethnical...
متن کاملRhodopsin mutations in Chinese patients with retinitis pigmentosa.
AIM To determine the pattern of rhodopsin mutations in Chinese retinitis pigmentosa (RP) patients. METHODS The rhodopsin gene was examined in 101 RP patients and 190 controls from Hong Kong. RESULTS Three coding changes were identified: Pro347Leu, Ala299Ser, and 5211delC. Each protein sequence alteration was found in one patient. Ala299Ser also existed in two controls. CONCLUSION The C-te...
