Our verdict is Likely benign. Variant got -6 ACMG points: 2P and 8B. PM2BP4_StrongBS2

The NM_031923.4(TAF3):​c.1403C>A​(p.Ala468Asp) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A468T) has been classified as Uncertain significance.

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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2023The c.1403C>A (p.A468D) alteration is located in exon 3 (coding exon 3) of the TAF3 gene. This alteration results from a C to A substitution at nucleotide position 1403, causing the alanine (A) at amino acid position 468 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
