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 Benign. Variant got -13 ACMG points.

• PP2: Missense variant where missense usually causes diseases, MED13
• BP4: Computational evidence support a benign effect (MetaRNN=0.002184242).
• BP6: Variant 17-61952972-G-A is Benign according to our data. Variant chr17-61952972-G-A is described in ClinVar as [Benign]. Clinvar id is 777207.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0127 (1940/152170) while in subpopulation AFR AF= 0.0442 (1835/41496). AF 95% confidence interval is 0.0425. There are 40 homozygotes in gnomad4. There are 911 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1940 AD gene.
