Genes affected

MED11 (HGNC:32687): (mediator complex subunit 11) MED11 is a component of the Mediator complex, which is a coactivator for DNA-binding factors that activate transcription via RNA polymerase II (Sato et al., 2003 [PubMed 12584197]).[supplied by OMIM, Oct 2008]

MED11 Gene-Disease associations (from GenCC):

• neurodegeneration with developmental delay, early respiratory failure, myoclonic seizures, and brain abnormalities

  Inheritance: AR Classification: STRONG, MODERATE, LIMITED Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae), G2P

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.31).
• BP7: Synonymous conserved (PhyloP=2.36 with no splicing effect.
