Genes affected

MED19 (HGNC:29600): (mediator complex subunit 19) The protein encoded by this gene is a subunit of the Mediator complex, which binds to gene-specific regulatory factors and provides support for the basal RNA polymerase II transcription machinery. This gene has been implicated in the growth of several types of cancer, and inhibition of its expression inhibits the growth and spread of these cancers. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]

The c.368A>G (p.D123G) alteration is located in exon 2 (coding exon 2) of the MED19 gene. This alteration results from a A to G substitution at nucleotide position 368, causing the aspartic acid (D) at amino acid position 123 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
