Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MED13L gene is commonly pathogenic or not. These statistics are base on transcript: NM_000015335.5. 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.;
Disease: DISEASE: Note=A chromosomal aberration involving MED13L is found in a patient with transposition of the great arteries, dextro- looped and mental retardation. Translocation t(12;17)(q24.1;q21). {ECO:0000269|PubMed:14638541}.; DISEASE: Mental retardation and distinctive facial features with or without cardiac defects (MRFACD) [MIM:616789]: An autosomal dominant, syndromic form of mental retardation characterized by delayed psychomotor development, profound language impairment, and facial dysmorphism, including frontal bossing, upslanting palpebral fissures, depressed nasal bridge with bulbous tip, and macrostomia. There is variable penetrance of cardiac malformations, ranging from no malformations to patent foramen ovale to septal defects and/or transposition of the great arteries. Mental retardation is defined by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. {ECO:0000269|PubMed:24781760, ECO:0000269|PubMed:25167861, ECO:0000269|PubMed:25356899, ECO:0000269|PubMed:25712080, ECO:0000269|PubMed:25758992}.
