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 made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.3).
BP6
Variant 11-93793780-C-T is Benign according to our data. Variant chr11-93793780-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 211483.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=2}.
BP7
Synonymous conserved (PhyloP=0.183 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00461 (702/152222) while in subpopulation AFR AF= 0.0159 (661/41512). AF 95% confidence interval is 0.0149. There are 5 homozygotes in gnomad4. There are 321 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 5 AR gene
