Invitae RCV001035399 SCV001198725 uncertain significance Hereditary sensory neuropathy-deafness-dementia syndrome 2019-03-07 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 DNMT1-related conditions. This variant is present in population databases (rs368319266, ExAC 0.001%). This sequence change replaces aspartic acid with asparagine at codon 718 of the DNMT1 protein (p.Asp718Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine.
