Labcorp Genetics (formerly Invitae), Labcorp RCV000692902 SCV000820751 uncertain significance Dihydropteridine reductase deficiency 2018-05-15 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine with tyrosine at codon 212 of the QDPR protein (p.Phe212Tyr). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and tyrosine. This variant is present in population databases (rs777797545, ExAC 0.009%). This variant has not been reported in the literature in individuals with QDPR-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function 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.
