Genes affected

MED24 (HGNC:22963): (mediator complex subunit 24) This gene encodes a component of the mediator complex (also known as TRAP, SMCC, DRIP, or ARC), a transcriptional coactivator complex thought to be required for the expression of almost all genes. The mediator complex is recruited by transcriptional activators or nuclear receptors to induce gene expression, possibly by interacting with RNA polymerase II and promoting the formation of a transcriptional pre-initiation complex. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.2606A>G (p.N869S) alteration is located in exon 23 (coding exon 22) of the MED24 gene. This alteration results from a A to G substitution at nucleotide position 2606, causing the asparagine (N) at amino acid position 869 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
