Labcorp Genetics (formerly Invitae), Labcorp RCV001984875 SCV002209457 uncertain significance Hereditary antithrombin deficiency 2021-06-25 criteria provided, single submitter clinical testing 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. This variant disrupts the p.Asn87 amino acid residue in SERPINC1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 29071478). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. This variant has been observed in individual(s) with clinical features of antithrombin III deficiency (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with serine at codon 87 of the SERPINC1 protein (p.Asn87Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine.
