Genes affected

TAF8 (HGNC:17300): (TATA-box binding protein associated factor 8) This gene encodes one of several TATA-binding protein (TBP)-associated factors (TAFs), which are integral subunits of the general transcription factor complex TFIID. TFIID recognizes the core promoter of many genes and nucleates the assembly of a transcription preinitiation complex containing RNA polymerase II and other initiation factors. The protein encoded by this gene contains an H4-like histone fold domain, and interacts with several subunits of TFIID including TBP and the histone-fold protein TAF10. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

The c.316A>G (p.T106A) alteration is located in exon 4 (coding exon 4) of the TAF8 gene. This alteration results from a A to G substitution at nucleotide position 316, causing the threonine (T) at amino acid position 106 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
