Genes affected

DKK4 (HGNC:2894): (dickkopf WNT signaling pathway inhibitor 4) 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. Activity of this protein is modulated by binding to the Wnt co-receptor and the co-factor kremen 2. [provided by RefSeq, Jul 2008]

The c.572T>C (p.F191S) alteration is located in exon 4 (coding exon 4) of the DKK4 gene. This alteration results from a T to C substitution at nucleotide position 572, causing the phenylalanine (F) at amino acid position 191 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
