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]

Our verdict: Benign. The variant received -21 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.71).

BP6

Variant 12-115970706-G-A is Benign according to our data. Variant chr12-115970706-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 415964.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-0.338 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00794 (1209/152324) while in subpopulation AFR AF = 0.0274 (1140/41562). AF 95% confidence interval is 0.0261. There are 24 homozygotes in GnomAd4. There are 556 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 1209 AD gene.
