Invitae | RCV001054694 | SCV001219042 | uncertain significance | Autosomal recessive nonsyndromic hearing loss 66; Isolated neonatal sclerosing cholangitis | 2019-02-05 | 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. 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: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DCDC2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with valine at codon 359 of the DCDC2 protein (p.Asp359Val). The aspartic acid residue is moderately conserved and there is a large physicochemical difference between aspartic acid and valine. |
