摘要: 视网膜色素变性(retinitis pigmentosa, RP)是一种遗传性进行性视细胞损伤性疾病,具有基因型和表型异质性。目前已鉴定的RP致病基因达到103个,其中有一类基因(PRPF3、PRPF4、PRPF6、PRPF8、PRPF31、SNRNP200、RP9和DHX38)与前体mRNA剪接相关,该类基因全身广泛表达,但其突变后引起RP这种组织特异性表型疾病的机制目前尚不清楚。现汇总近年来国内外研究进展,介绍前体mRNA的剪接过程、前体mRNA剪接因子在剪接过程中的作用及前体mRNA剪接因子导致RP的疾病模型,并探讨前体mRNA剪接因子突变导致RP的致病机制。

Abstract: Retinitis pigmentosa(RP)is an inherited disease of progressive damage to visual cells with genotypic and phenotypic heterogeneity. Up to now, 103 RP pathogenic genes have been identified, among which there is a type of genes(PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, RP9, and DHX38)that is related to pre-mRNA splicing. This type of genes is widely expressed throughout the body, but its mutation, the mechanism behind the disease that causes this tissue-specific phenotype of RP is currently unclear. This paper summarized the research progress in recent years,introduced the splicing process of pre-mRNA, the role of pre-mRNA splicing factors in the splicing process, and the disease model of RP caused by pre-mRNA splicing factors, and discussed the mutations of pre-mRNA splicing factors contribute to the pathogenic mechanism of RP.

Key words: retinitis pigmentosa, pre-mRNA processing factors, disease models, pathogenic mechanism
