Labcorp Genetics (formerly Invitae), Labcorp RCV001938807 SCV002202374 uncertain significance DNA ligase IV deficiency 2023-08-17 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. 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 expected to disrupt LIG4 protein function. ClinVar contains an entry for this variant (Variation ID: 1429192). This variant has not been reported in the literature in individuals affected with LIG4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 679 of the LIG4 protein (p.Glu679Lys).
