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]

Feb 28, 2024

The c.266C>T (p.T89M) alteration is located in exon 3 (coding exon 3) of the MED12L gene. This alteration results from a C to T substitution at nucleotide position 266, causing the threonine (T) at amino acid position 89 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
