Invitae RCV001212331 SCV001383912 uncertain significance Autosomal recessive polycystic kidney disease 2021-08-27 criteria provided, single submitter clinical testing This sequence change replaces cysteine with tyrosine at codon 2965 of the PKHD1 protein (p.Cys2965Tyr). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is not present in population databases (ExAC no frequency). This missense change has been observed in individual(s) with polycystic kidney disease (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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 (PMID: 16133180), which suggests that this may be a clinically significant amino acid residue. 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.
