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.758A>G (p.D253G) alteration is located in exon 6 (coding exon 5) of the TAF1D gene. This alteration results from a A to G substitution at nucleotide position 758, causing the aspartic acid (D) at amino acid position 253 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
