Genes affected

MED12L (HGNC:16050): (mediator complex subunit 12L) The protein encoded by this gene is part of the Mediator complex, which is involved in transcriptional coactivation of nearly all RNA polymerase II-dependent genes. The Mediator complex links gene-specific transcriptional activators with the basal transcription machinery. [provided by RefSeq, May 2010]

Collection Method: clinical testing

The c.32A>G (p.Q11R) alteration is located in exon 1 (coding exon 1) of the MED12L gene. This alteration results from a A to G substitution at nucleotide position 32, causing the glutamine (Q) at amino acid position 11 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
