Genes affected

SETDB1 (HGNC:10761): (SET domain bifurcated histone lysine methyltransferase 1) This gene encodes a histone methyltransferase which regulates histone methylation, gene silencing, and transcriptional repression. This gene has been identified as a target for treatment in Huntington Disease, given that gene silencing and transcription dysfunction likely play a role in the disease pathogenesis. Alternatively spliced transcript variants of this gene have been described.[provided by RefSeq, Jun 2011]

ACMG classification

Our verdict: Benign. The variant received -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 1-150949261-C-G is Benign according to our data. Variant chr1-150949261-C-G is described in ClinVar as [Benign]. Clinvar id is 722333.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-3.13 with no splicing effect.
• BS2: High AC in GnomAd4 at 188 AD gene.
