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.2389A>G (p.K797E) alteration is located in exon 21 (coding exon 20) of the MED24 gene. This alteration results from a A to G substitution at nucleotide position 2389, causing the lysine (K) at amino acid position 797 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
