Genes affected

MED13 (HGNC:22474): (mediator complex subunit 13) This gene encodes a component of the mediator complex (also known as TRAP, SMCC, DRIP, or ARC), a transcriptional coactivator complex thought to be required for the expression of almost all genes. The mediator complex is recruited by transcriptional activators or nuclear receptors to induce gene expression, possibly by interacting with RNA polymerase II and promoting the formation of a transcriptional pre-initiation complex. The product of this gene is proposed to form a sub-complex with MED12, cyclin C, and CDK8 that can negatively regulate transactivation by mediator. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MED13. . Gene score misZ 2.6232 (greater than the threshold 3.09). Trascript score misZ 3.3083 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, intellectual developmental disorder 61, complex neurodevelopmental disorder.
• BP4: Computational evidence support a benign effect (MetaRNN=0.38302216).
