Labcorp Genetics (formerly Invitae), Labcorp RCV001280137 SCV003019116 uncertain significance Ornithine aminotransferase deficiency 2022-08-01 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 419 of the OAT protein (p.Val419Leu). This variant is present in population databases (rs760922693, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with OAT-related conditions. ClinVar contains an entry for this variant (Variation ID: 991854). 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. 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.
Ambry Genetics RCV004035502 SCV004994431 uncertain significance Inborn genetic diseases 2021-06-22 criteria provided, single submitter clinical testing The c.1255G>C (p.V419L) alteration is located in exon 10 (coding exon 9) of the OAT gene. This alteration results from a G to C substitution at nucleotide position 1255, causing the valine (V) at amino acid position 419 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
