Genes affected

MED17 (HGNC:2375): (mediator complex subunit 17) The activation of gene transcription is a multistep process that is triggered by factors that recognize transcriptional enhancer sites in DNA. These factors work with co-activators to direct transcriptional initiation by the RNA polymerase II apparatus. The protein encoded by this gene is a subunit of the CRSP (cofactor required for SP1 activation) complex, which, along with TFIID, is required for efficient activation by SP1. This protein is also a component of other multisubunit complexes e.g. thyroid hormone receptor-(TR-) associated proteins which interact with TR and facilitate TR function on DNA templates in conjunction with initiation factors and cofactors.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0019546747).

BP6

Variant 11-93796468-T-A is Benign according to our data. Variant chr11-93796468-T-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 129596.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00803 (1223/152354) while in subpopulation AFR AF = 0.027 (1121/41582). AF 95% confidence interval is 0.0256. There are 18 homozygotes in GnomAd4. There are 600 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 18 AR gene
