Genes affected

NKD1 (HGNC:17045): (NKD inhibitor of WNT signaling pathway 1) In the mouse, Nkd is a Dishevelled (see DVL1; MIM 601365)-binding protein that functions as a negative regulator of the Wnt (see WNT1; MIM 164820)-beta-catenin (see MIM 116806)-Tcf (see MIM 602272) signaling pathway.[supplied by OMIM, Jun 2003]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0119 (1810/152074) while in subpopulation AFR AF= 0.0407 (1685/41448). AF 95% confidence interval is 0.039. There are 42 homozygotes in gnomad4. There are 857 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1810 AD gene.
