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]

The c.496G>T (p.V166L) alteration is located in exon 7 (coding exon 7) of the NKD1 gene. This alteration results from a G to T substitution at nucleotide position 496, causing the valine (V) at amino acid position 166 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
