Invitae RCV001063278 SCV001228116 uncertain significance D-2-hydroxyglutaric aciduria 1 2019-03-28 criteria provided, single submitter clinical testing This sequence change replaces cysteine with tyrosine at codon 172 of the D2HGDH protein (p.Cys172Tyr). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is present in population databases (rs773735172, ExAC 0.003%). This variant has been observed in an individual affected with D-2-Hydroxyglutaric aciduria (PMID: 20020533). 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: Probably 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.
