Genes affected

TAF1C (HGNC:11534): (TATA-box binding protein associated factor, RNA polymerase I subunit C) Initiation of transcription by RNA polymerase I requires the formation of a complex composed of the TATA-binding protein (TBP) and three TBP-associated factors (TAFs) specific for RNA polymerase I. This complex, known as SL1, binds to the core promoter of ribosomal RNA genes to position the polymerase properly and acts as a channel for regulatory signals. This gene encodes the largest SL1-specific TAF. Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2011]

The c.2440A>G (p.M814V) alteration is located in exon 14 (coding exon 13) of the TAF1C gene. This alteration results from a A to G substitution at nucleotide position 2440, causing the methionine (M) at amino acid position 814 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
