Genes affected

MED12 (HGNC:11957): (mediator complex subunit 12) The initiation of transcription is controlled in part by a large protein assembly known as the preinitiation complex. A component of this preinitiation complex is a 1.2 MDa protein aggregate called Mediator. This Mediator component binds with a CDK8 subcomplex which contains the protein encoded by this gene, mediator complex subunit 12 (MED12), along with MED13, CDK8 kinase, and cyclin C. The CDK8 subcomplex modulates Mediator-polymerase II interactions and thereby regulates transcription initiation and reinitation rates. The MED12 protein is essential for activating CDK8 kinase. Defects in this gene cause X-linked Opitz-Kaveggia syndrome, also known as FG syndrome, and Lujan-Fryns syndrome. [provided by RefSeq, Aug 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PP2

Missense variant in the MED12 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 37 curated pathogenic missense variants (we use a threshold of 10). The gene has 108 curated benign missense variants. Gene score misZ: 6.5797 (above the threshold of 3.09). GenCC associations: The gene is linked to MED12-related intellectual disability syndrome, X-linked intellectual disability with marfanoid habitus, blepharophimosis - intellectual disability syndrome, MKB type, FG syndrome 1, cholestasis-pigmentary retinopathy-cleft palate syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.13404664).

BP6

Variant X-71130195-G-A is Benign according to our data. Variant chrX-71130195-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 220794.Status of the report is criteria_provided_single_submitter, 1 stars.
