Description
For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects RHO function (PMID: 30977563). 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 RHO protein function. This missense change has been observed in individuals with autosomal dominant retinosis pigmentaria (PMID: 19958124, 23402891; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 78 of the RHO protein (p.Asn78Ile).
