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 made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.56).
BP6
Variant 3-47121648-T-C is Benign according to our data. Variant chr3-47121648-T-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 475505.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}. Variant chr3-47121648-T-C is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=0.327 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0000267 (39/1461792) while in subpopulation AFR AF= 0.000418 (14/33478). AF 95% confidence interval is 0.000252. There are 0 homozygotes in gnomad4_exome. There are 18 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
High AC in GnomAdExome4 at 39 AD gene.
