Invitae RCV003508589 SCV004281933 uncertain significance Holoprosencephaly 5 2023-06-15 criteria provided, single submitter clinical testing 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 ZIC2 protein function. This variant has not been reported in the literature in individuals affected with ZIC2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.02%). This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 185 of the ZIC2 protein (p.Gly185Asp).
