Invitae RCV003523054 SCV004278646 uncertain significance Hajdu-Cheney syndrome 2023-06-15 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with NOTCH2-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 NOTCH2 protein function. ClinVar contains an entry for this variant (Variation ID: 806200). This variant is present in population databases (rs774541297, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 1564 of the NOTCH2 protein (p.Ser1564Arg).
