Labcorp Genetics (formerly Invitae), Labcorp RCV003061289 SCV003461073 uncertain significance Kabuki syndrome 2 2024-02-14 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 446 of the KDM6A protein (p.Ser446Cys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with intellectual disability (PMID: 29302074). ClinVar contains an entry for this variant (Variation ID: 2151339). 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 KDM6A protein function with a negative 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.
