Genes affected

BTAF1 (HGNC:17307): (B-TFIID TATA-box binding protein associated factor 1) This gene encodes a TAF (TATA box-binding protein-associated factor), which associates with TBP (TATA box-binding protein) to form the B-TFIID complex that is required for transcription initiation of genes by RNA polymerase II. This TAF has DNA-dependent ATPase activity, which drives the dissociation of TBP from DNA, freeing the TBP to associate with other TATA boxes or TATA-less promoters. [provided by RefSeq, Sep 2011]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PP2: Missense variant where missense usually causes diseases, BTAF1
• BP4: Computational evidence support a benign effect (MetaRNN=0.16930383).
• BS2: High AC in GnomAdExome4 at 29 AD gene.
