Neuberg Centre For Genomic Medicine, NCGM RCV001089876 SCV004048409 uncertain significance Ornithine carbamoyltransferase deficiency criteria provided, single submitter clinical testing The missense variant in c.1009G>T(p.Val337Phe) in OTC gene has been submitted to ClinVar as Pathogenic, but no details are available for independent assessment. It has not been reported in affected individuals. The p.Val337Phe variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. The variant is predicted to be damaging by both SIFT and PolyPhen2. The amino acid Val at position 337 is changed to a Phe changing protein sequence and it might alter its composition and physico-chemical properties. The residue is conserved across species. The amino acid change p.Val337Phe in OTC is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
