- ArticleLu F, Huang L, Lei C, Sha G, Zheng H, Liu X, Yang J, Shi Y, Lin Y, Gong B, Zhu X, Ma S, Qiao L, Lin H, Cheng J, Yang Z.PLoS One. 2013;8(11):e78274.PURPOSE: This study was intended to identify the disease causing genes in a large Chinese family with autosomal dominant retinitis pigmentosa and macular degeneration.
METHODS: A genome scan analysis was conducted in this family for disease gene preliminary mapping. Snapshot analysis of selected SNPs for two-point LOD score analysis for candidate gene filter. Candidate gene PRPF31 whole exons' sequencing was executed to identify mutations.
RESULTS: A novel nonsense mutation caused by an insertion was found in PRPF31 gene. All the 19 RP patients in 1085 family are carrying this heterozygous nonsense mutation. The nonsense mutation is in PRPF31 gene exon9 at chr19:54629961-54629961, inserting nucleotide "A" that generates the coding protein frame shift from p.307 and early termination at p.322 in the snoRNA binding domain (NOP domain).
CONCLUSION: This report is the first to associate PRPF31 gene's nonsense mutation and adRP and JMD. Our findings revealed that PRPF31 can lead to different clinical phenotypes in the same family, resulting either in adRP or syndrome of adRP and JMD. We believe our identification of the novel "A" insertion mutation in exon9 at chr19:54629961-54629961 in PRPF31 can provide further genetic evidence for clinical test for adRP and JMD. - Bookedited by Ronald Cohn, Stephen Scherer, Ada Hamosh.Summary: First published in 1966, Thompson and Thompson Genetics and Genomics in Medicine has become an essential textbook for medical students, genetic counseling students, students in laboratory medicine, and more advanced trainees. With its focus on fundamental principles in human genetics and genomics and their application to medicine, the book has served many as a well-thumbed resource they return to over and over. Such students can continue to depend on this valuable text, joining those in newer fields of genome data analysis for all they need to know about genetics and genomics throughout their basic science training, clinical placements and beyond. Coverage includes new discoveries--such as the functional roles of non-coding RNAs, chromatin regulation and epigenetics--latest technologies, and new diagnoses they are enabling.
