Invitae RCV001889272 SCV002159821 uncertain significance Autosomal recessive polycystic kidney disease 2020-11-14 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with PKHD1-related conditions. 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. 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. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with aspartic acid at codon 791 of the PKHD1 protein (p.His791Asp). The histidine residue is weakly conserved and there is a moderate physicochemical difference between histidine and aspartic acid.
