Genes affected
DKK3 (HGNC:2893): (dickkopf WNT signaling pathway inhibitor 3) This gene encodes a protein that is a member of the dickkopf family. The secreted protein contains two cysteine rich regions and is involved in embryonic development through its interactions with the Wnt signaling pathway. The expression of this gene is decreased in a variety of cancer cell lines and it may function as a tumor suppressor gene. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.002554059).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0129 (1967/152328) while in subpopulation AFR AF = 0.0451 (1874/41574). AF 95% confidence interval is 0.0434. There are 46 homozygotes in GnomAd4. There are 942 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAd4 at 46 AR gene
