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]
PRPF31-AS1 (HGNC:40700): (PRPF31 antisense RNA 1)

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 28, 2023This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 84 of the PRPF31 protein (p.Val84Ala). This variant is present in population databases (rs369049017, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PRPF31-related conditions. ClinVar contains an entry for this variant (Variation ID: 1471211). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
