Genes affected

DKK1 (HGNC:2891): (dickkopf WNT signaling pathway inhibitor 1) This gene encodes a member of the dickkopf family of proteins. Members of this family are secreted proteins characterized by two cysteine-rich domains that mediate protein-protein interactions. The encoded protein binds to the LRP6 co-receptor and inhibits beta-catenin-dependent Wnt signaling. This gene plays a role in embryonic development and may be important in bone formation in adults. Elevated expression of this gene has been observed in numerous human cancers and this protein may promote proliferation, invasion and growth in cancer cell lines. [provided by RefSeq, Sep 2017]

The c.247T>C (p.Y83H) alteration is located in exon 2 (coding exon 2) of the DKK1 gene. This alteration results from a T to C substitution at nucleotide position 247, causing the tyrosine (Y) at amino acid position 83 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
