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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.221C>A (p.T74K) alteration is located in exon 4 (coding exon 4) of the NKD1 gene. This alteration results from a C to A substitution at nucleotide position 221, causing the threonine (T) at amino acid position 74 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
