Labcorp Genetics (formerly Invitae), Labcorp RCV002015598 SCV002288400 uncertain significance Neu-Laxova syndrome 2 2024-10-23 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 279 of the PSAT1 protein (p.Tyr279His). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PSAT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1500377). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt PSAT1 protein function with a positive predictive value of 80%. 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.
