Genes affected

TAF1A (HGNC:11532): (TATA-box binding protein associated factor, RNA polymerase I subunit A) This gene encodes a subunit of the RNA polymerase I complex, Selectivity Factor I (SLI). The encoded protein is a TATA box-binding protein-associated factor that plays a role in the assembly of the RNA polymerase I preinitiation complex. Alternate splicing results in multiple transcript variants encoding multiple isoforms.[provided by RefSeq, Jan 2011]

The c.1310A>G (p.K437R) alteration is located in exon 11 (coding exon 10) of the TAF1A gene. This alteration results from a A to G substitution at nucleotide position 1310, causing the lysine (K) at amino acid position 437 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
