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]

The c.571C>G (p.Q191E) alteration is located in exon 6 (coding exon 6) of the BTAF1 gene. This alteration results from a C to G substitution at nucleotide position 571, causing the glutamine (Q) at amino acid position 191 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
