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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.775A>T (p.N259Y) alteration is located in exon 7 (coding exon 7) of the BTAF1 gene. This alteration results from a A to T substitution at nucleotide position 775, causing the asparagine (N) at amino acid position 259 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
