Invitae | RCV001204440 | SCV001375646 | uncertain significance | Nephronophthisis 15 | 2023-12-11 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 622 of the CEP164 protein (p.Arg622Trp). This variant is present in population databases (rs760666687, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CEP164-related conditions. ClinVar contains an entry for this variant (Variation ID: 935778). 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 CEP164 protein function with a negative predictive value of 80%. 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. |
