ClinVar

Description

For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg2310 amino acid residue in PRPF8. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11468273, 12714658, 16799052, 28515276). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PRPF8 protein function. ClinVar contains an entry for this variant (Variation ID: 30667). This missense change has been observed in individuals with autosomal dominant retinitis pigmentosa (PMID: 20232351, 30360737). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 2310 of the PRPF8 protein (p.Arg2310Ser).
