Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MED12 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000005120.3. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. This subunit may specifically regulate transcription of targets of the Wnt signaling pathway and SHH signaling pathway. {ECO:0000269|PubMed:16565090, ECO:0000269|PubMed:16595664, ECO:0000269|PubMed:17000779}.;
Disease
DISEASE: Lujan-Fryns syndrome (LUJFRYS) [MIM:309520]: Clinically, Lujan-Fryns syndrome can be distinguished from Opitz-Kaveggia syndrome by tall stature, hypernasal voice, hyperextensible digits and high nasal root. {ECO:0000269|PubMed:17369503}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Ohdo syndrome, X-linked (OHDOX) [MIM:300895]: A syndrome characterized by mental retardation, feeding problems, and distinctive facial appearance with coarse facial features, severe blepharophimosis, ptosis, a bulbous nose, micrognathia and a small mouth. Dental hypoplasia and deafness can be considered as common manifestations of the syndrome. Male patients show cryptorchidism and scrotal hypoplasia. {ECO:0000269|PubMed:23395478}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
