Labcorp Genetics (formerly Invitae), Labcorp RCV001890274 SCV002149669 uncertain significance Hereditary antithrombin deficiency 2023-12-21 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 423 of the SERPINC1 protein (p.Ala423Thr). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This missense change has been observed in individual(s) with SERPINC1-related conditions (PMID: 25312341). This variant is also known as p.A391T. ClinVar contains an entry for this variant (Variation ID: 1382422). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SERPINC1 protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects SERPINC1 function (PMID: 25312341). 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.
