Description

This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 494 of the FLVCR1 protein (p.Asn494Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with retinitis pigmentosa (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 852309). 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 FLVCR1 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic.
