Invitae RCV000672675 SCV003439427 pathogenic Autosomal recessive polycystic kidney disease 2022-06-14 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Cys2965 amino acid residue in PKHD1. Other variant(s) that disrupt this residue have been observed in individuals with PKHD1-related conditions (Invitae), which suggests that this may be a clinically significant amino acid residue. 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 PKHD1 protein function. ClinVar contains an entry for this variant (Variation ID: 556643). This missense change has been observed in individual(s) with autosomal recessive polycystic kidney disease (PMID: 16133180, 33532864). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 2965 of the PKHD1 protein (p.Cys2965Arg).
