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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.1329385).

The c.1126C>G (p.Q376E) alteration is located in exon 3 (coding exon 3) of the TAF3 gene. This alteration results from a C to G substitution at nucleotide position 1126, causing the glutamine (Q) at amino acid position 376 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
