Labcorp Genetics (formerly Invitae), Labcorp RCV003753149 SCV004383401 uncertain significance Kabuki syndrome 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 3147 of the KMT2D protein (p.Ala3147Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with KMT2D-related conditions. ClinVar contains an entry for this variant (Variation ID: 547462). 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 KMT2D protein function with a negative predictive value of 95%. 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.
