Genes affected

DKK3 (HGNC:2893): (dickkopf WNT signaling pathway inhibitor 3) 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. The expression of this gene is decreased in a variety of cancer cell lines and it may function as a tumor suppressor gene. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

The c.611A>G (p.N204S) alteration is located in exon 6 (coding exon 5) of the DKK3 gene. This alteration results from a A to G substitution at nucleotide position 611, causing the asparagine (N) at amino acid position 204 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
