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.148T>G (p.F50V) alteration is located in exon 2 (coding exon 2) of the TAF8 gene. This alteration results from a T to G substitution at nucleotide position 148, causing the phenylalanine (F) at amino acid position 50 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
