Genes affected

TAF1D (HGNC:28759): (TATA-box binding protein associated factor, RNA polymerase I subunit D) TAF1D is a member of the SL1 complex, which includes TBP (MIM 600075) and TAF1A (MIM 604903), TAF1B (MIM 604904), and TAF1C (MIM 604905), and plays a role in RNA polymerase I transcription (Wang et al., 2004 [PubMed 15520167]; Gorski et al., 2007 [PubMed 17318177]).[supplied by OMIM, Jun 2009]

The c.421G>A (p.E141K) alteration is located in exon 3 (coding exon 2) of the TAF1D gene. This alteration results from a G to A substitution at nucleotide position 421, causing the glutamic acid (E) at amino acid position 141 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
