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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.04010451).
BP6
Variant 3-47122481-T-C is Benign according to our data. Variant chr3-47122481-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 135211.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000112 (17/152362) while in subpopulation SAS AF = 0.00124 (6/4832). AF 95% confidence interval is 0.000541. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 17 AD gene.
