Description
For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Asn15 amino acid residue in RHO. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8353500, 9483582, 31100078). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 not expected to disrupt RHO protein function. ClinVar contains an entry for this variant (Variation ID: 802004). This missense change has been observed in individuals with autosomal dominant retinitis pigmentosa (PMID: 30538586; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 15 of the RHO protein (p.Asn15Lys).
