Labcorp Genetics (formerly Invitae), Labcorp RCV001063477 SCV001228324 pathogenic Ornithine carbamoyltransferase deficiency 2022-03-15 criteria provided, single submitter clinical testing This missense change has been observed in individuals with ornithine transcarbamylase deficiency (PMID: 16786505, 18662984, 29123827; Invitae). This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 345 of the OTC protein (p.Tyr345His). This variant is not present in population databases (gnomAD no frequency). ClinVar contains an entry for this variant (Variation ID: 97100). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant disrupts the p.Tyr345 amino acid residue in OTC. Other variant(s) that disrupt this residue have been observed in individuals with OTC-related conditions (PMID: 1480464, 10946359), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic.
