Genes affected

KDM6A (HGNC:12637): (lysine demethylase 6A) This gene is located on the X chromosome and is the corresponding locus to a Y-linked gene which encodes a tetratricopeptide repeat (TPR) protein. The encoded protein of this gene contains a JmjC-domain and catalyzes the demethylation of tri/dimethylated histone H3. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Apr 2014]

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 not expected to disrupt KDM6A protein function. ClinVar contains an entry for this variant (Variation ID: 1037454). This variant has not been reported in the literature in individuals affected with KDM6A-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.008%), including at least one homozygous and/or hemizygous individual. This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 519 of the KDM6A protein (p.Arg519Gly). -
