Invitae RCV000011747 SCV000825697 pathogenic Ornithine carbamoyltransferase deficiency 2018-09-05 criteria provided, single submitter clinical testing This sequence change replaces proline with leucine at codon 225 of the OTC protein (p.Pro225Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine. This variant is not present in population databases (ExAC no frequency). This variant has been reported to segregate with ornithine transcarbamylase (OTC) deficiency in a family (PMID: 1721894) and has been reported in individuals affected with this condition (PMID: 27070778, 9427144, 9286441). ClinVar contains an entry for this variant (Variation ID: 11000). 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"). Other missense substitutions at this codon (p.PRo225Arg and p.Pro225Thr) have been reported in individuals affected with ornithine transcarbamylase (OTC) deficiency (PMID: 9427144, 19669271, 10946359). For these reasons, this variant has been classified as Pathogenic.
