ARC240; CAGH45; FGS1; HOPA; MED12S; OHDOX; OKS; OPA1; TNRC11; TRAP230

Associated disorders

The MED12 gene is associated with X-linked recessive Lujan-Fryns syndrome (LFS) (MedGen UID: 167096), Opitz-Kaveggia syndrome (OKS) (MedGen UID: 113106), and Ohdo syndrome (MedGen UID: 785805). Additionally, the MED12 gene has preliminary evidence supporting a correlation with X-linked recessive intellectual disability (ID) (PMID: 26273451, 25644381).

Invitae tests that include this gene:

Pathogenic MED12 variants are a rare cause of X-linked FG, Lujan, and Ohdo syndromes.

The MED12 gene encodes a subunit of the macromolecular complex known as Mediator, which plays a central role in thyroid hormone‰ÛÒdependent activation and repression of transcription by RNA polymerase II. The mediator complex serves as an interface between transcription factors and RNA polymerase II (PMID: 24123922).

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
