Genes affected

TAF3 (HGNC:17303): (TATA-box binding protein associated factor 3) The highly conserved RNA polymerase II transcription factor TFIID (see TAF1; MIM 313650) comprises the TATA box-binding protein (TBP; MIM 600075) and a set of TBP-associated factors (TAFs), including TAF3. TAFs contribute to promoter recognition and selectivity and act as antiapoptotic factors (Gangloff et al., 2001 [PubMed 11438666]).[supplied by OMIM, May 2009]

The c.881T>C (p.M294T) alteration is located in exon 3 (coding exon 3) of the TAF3 gene. This alteration results from a T to C substitution at nucleotide position 881, causing the methionine (M) at amino acid position 294 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
