Genes affected
PRPF31 (HGNC:15446): (pre-mRNA processing factor 31) This gene encodes a component of the spliceosome complex and is one of several retinitis pigmentosa-causing genes. When the gene product is added to the spliceosome complex, activation occurs.[provided by RefSeq, Jan 2009]

Submissions by phenotype

not provided Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 03, 2022For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Disruption of the initiator codon has been observed in individuals with retinitis pigmentosa (PMID: 28041643; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the PRPF31 mRNA. The next in-frame methionine is located at codon 59. -
