Genes affected

MED13 (HGNC:22474): (mediator complex subunit 13) 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. The product of this gene is proposed to form a sub-complex with MED12, cyclin C, and CDK8 that can negatively regulate transactivation by mediator. [provided by RefSeq, Jul 2008]

Ambry Genetics

Apr 25, 2023

The c.6450G>T (p.Q2150H) alteration is located in exon 30 (coding exon 30) of the MED13 gene. This alteration results from a G to T substitution at nucleotide position 6450, causing the glutamine (Q) at amino acid position 2150 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
