Invitae RCV000662117 SCV001229674 uncertain significance Frontotemporal dementia 2019-02-12 criteria provided, single submitter clinical testing This sequence change replaces glycine with valine at codon 16 of the MAPT protein (p.Gly16Val). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and valine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with MAPT-related conditions. ClinVar contains an entry for this variant (Variation ID: 548576). 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: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
