Genes affected
SETD2 (HGNC:18420): (SET domain containing 2, histone lysine methyltransferase) Huntington's disease (HD), a neurodegenerative disorder characterized by loss of striatal neurons, is caused by an expansion of a polyglutamine tract in the HD protein huntingtin. This gene encodes a protein belonging to a class of huntingtin interacting proteins characterized by WW motifs. This protein is a histone methyltransferase that is specific for lysine-36 of histone H3, and methylation of this residue is associated with active chromatin. This protein also contains a novel transcriptional activation domain and has been found associated with hyperphosphorylated RNA polymerase II. [provided by RefSeq, Aug 2008]

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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 542226). This variant has not been reported in the literature in individuals affected with SETD2-related conditions. This variant is present in population databases (rs200569407, gnomAD 0.01%). This sequence change replaces leucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 981 of the SETD2 protein (p.Leu981Ser). -
