Genes affected

ZNF335 (HGNC:15807): (zinc finger protein 335) The protein encoded by this gene enhances transcriptional activation by ligand-bound nuclear hormone receptors. However, it does this not by direct interaction with the receptor, but by direct interaction with the nuclear hormone receptor transcriptional coactivator NRC. The encoded protein may function by altering local chromatin structure. [provided by RefSeq, Jul 2008]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.8).

BP6

Variant 20-45950050-G-A is Benign according to our data. Variant chr20-45950050-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 130805.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-0.048 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00384 (585/152330) while in subpopulation AFR AF = 0.0127 (526/41566). AF 95% confidence interval is 0.0118. There are 5 homozygotes in GnomAd4. There are 288 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AR gene
