Genes affected
DKK2 (HGNC:2892): (dickkopf WNT signaling pathway inhibitor 2) 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. It can act as either an agonist or antagonist of Wnt/beta-catenin signaling, depending on the cellular context and the presence of the co-factor kremen 2. Activity of this protein is also modulated by binding to the Wnt co-receptor LDL-receptor related protein 6 (LRP6). [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2022The c.292T>C (p.S98P) alteration is located in exon 2 (coding exon 2) of the DKK2 gene. This alteration results from a T to C substitution at nucleotide position 292, causing the serine (S) at amino acid position 98 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
