Labcorp Genetics (formerly Invitae), Labcorp RCV003758088 SCV004511551 uncertain significance Developmental and epileptic encephalopathy, 54 2023-10-17 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 345 of the HNRNPU protein (p.Pro345Leu). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with HNRNPU-related conditions. 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 HNRNPU protein function. 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.
