PRPF8

PRPF8

A gene on chromosome 17p13.3 that encodes protein which is a central component of the spliceosome and thought to play a role in aligning pre-mRNA 5'- and 3'-exons for ligation. It interacts with U5 snRNP proteins SNRP116 and WDR57/SPF38, and with EFTUD2 and SNRNP200.

Molecular pathology
Defects in PRPF8 cause retinitis pigmentosa type 13.

Of other genes that can cause autosomal dominant RP include RP1 [8q12.1], PRPF3 (pre-MRNA processing factor 3) [1q21.2], PRPF8 [17p13.3], and PRPF31 [19q13.42] have been identified to contribute 5.5%, 4%, 2%, and 5%, respectively.
There are eight JAMM domain proteins in human, including PRPF8 without protease activity [51, 54].

A recent epigenome-wide association study (EGWAS) in whole-blood DNA of patients from Atherosclerosis Risk in Communities (ARIC) and Framingham Heart (FHS) studies, analyzed using regression models with residualized methylation [beta]-values as the independent variable, showed a statistically significant association between the DNA methylation level in specific CpG sites (e.g., cg23597162 in JAZF1; cg19942083 in PTPN6/PHB2; and cg17944885 in ZNF788/ ZNF20) and the reduction in glomerular filtration rate (eGFR), prevalence and incidence of CKD (cg17944885 and cg19942083 in PTPN6/PHB2), or renal fibrosis (cg12065228 in PQLC2, intergenic cg19942083 near PTPN6/PHB2, cg12116137 in PRPF8, cg09022230 in TNRC18, and cg27660627 in ANKRD11).
Next-generation sequencing (NGS) was then applied to two affected family members with RP (III:9 and IV:1), who did not have CYP4V2 mutations, then to identify disease-causing variants in 47 RP-related genes including the PRPF31, CRB1, PRPF8, CA4, TULP1, PRPF3, ABCA4, RPE65, EYS, CERKL, NRL, FAM161A, FSCN2, TOPORS, SNRNP200, SEMA4A, PRCD, NR2E3, MERTK, USH2A, PDE6B, PROM1, KLHL7, PDE6A, RGR, CNGB1, IDH3B, SAG, GUCA1B, CNGA1, BEST1, TTC8, C2orf71, ARL6, IMPG2, PDE6G, ZNF513, DHDDS, PRPF6, CLRN1, MAK, CDHR1, FLVCR1, RLBP1, SPATA7, AIPL1, and LRAT genes.
