Invitae RCV002607486 SCV003510604 uncertain significance Autosomal recessive polycystic kidney disease 2022-08-22 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 1438 of the PKHD1 protein (p.Asp1438Glu). This variant is present in population databases (rs369879082, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with PKHD1-related conditions. 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 PKHD1 protein function. 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.
