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]

ACMG classification

Verdict is Benign. Variant got -19 ACMG points.

• PP2: Missense variant where missense usually causes diseases, SETD2
• BP4: Computational evidence support a benign effect (MetaRNN=0.0015663505).
• BP6: Variant 3-47121932-C-G is Benign according to our data. Variant chr3-47121932-C-G is described in ClinVar as [Benign]. Clinvar id is 135230.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-47121932-C-G is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.214 is higher than 0.05.
