Labcorp Genetics (formerly Invitae), Labcorp RCV005192240 SCV005829768 uncertain significance Kabuki syndrome 2 2024-06-16 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 252 of the KDM6A protein (p.Met252Leu). This variant is present in population databases (rs376747068, gnomAD 0.001%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with KDM6A-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 KDM6A 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.
