Invitae RCV001371891 SCV001568475 uncertain significance 3-Methylglutaconic aciduria type 2 2022-05-27 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 219 of the TAZ protein (p.Asp219Glu). This variant is present in population databases (rs140751478, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with TAZ-related conditions. ClinVar contains an entry for this variant (Variation ID: 978376). 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: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.
