Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BS1 BS2

The NM_031923.4(TAF3):​c.1046G>C​(p.Ser349Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0435 in 1,613,814 control chromosomes in the GnomAD database, including 1,730 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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 Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0026902258).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0322 (4896/152144) while in subpopulation NFE AF= 0.0461 (3133/67984). AF 95% confidence interval is 0.0447. There are 105 homozygotes in gnomad4. There are 2371 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 4896 AD gene.
