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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 08, 2024The c.2525G>C (p.S842T) alteration is located in exon 14 (coding exon 13) of the TAF1C gene. This alteration results from a G to C substitution at nucleotide position 2525, causing the serine (S) at amino acid position 842 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
