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]

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	New York Genome Center	Apr 18, 2020	The p.Lys611Asn variant identified in SETD2 has not been reported in affected individuals in the literature. The variant has 0.000043 allele frequency in gnomAD database (12 out of 279,304 heterozygous alleles) indicating it is a rare allele in general population. The variant affects a moderately conserved residue andin silico prediction tools show conflicting interpretations about pathogenicity of this variant. Based on the current evidence, the p.Lys611Asn variant in the SETD2 gene is assessed as a variant of uncertain significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Genome-Nilou Lab	Mar 15, 2022	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 26, 2020	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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with SETD2-related conditions. This variant is present in population databases (rs575862721, ExAC 0.006%). This sequence change replaces lysine with asparagine at codon 611 of the SETD2 protein (p.Lys611Asn). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and asparagine. -
