Genes affected

MED13L (HGNC:22962): (mediator complex subunit 13L) The protein encoded by this gene is a subunit of the Mediator complex, a large complex of proteins that functions as a transcriptional coactivator for most RNA polymerase II-transcribed genes. The encoded protein is involved in early development of the heart and brain. Defects in this gene are a cause of transposition of the great arteries, dextro-looped (DTGA).[provided by RefSeq, Jul 2010]

MED13L (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 12-116007542-G-A is Pathogenic according to our data. Variant chr12-116007542-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 545567.Status of the report is criteria_provided_single_submitter, 1 stars.
