Genes affected

DKKL1 (HGNC:16528): (dickkopf like acrosomal protein 1) The dickkopf protein family interacts with the Wnt signaling pathway and its members are characterized by two conserved cysteine-rich domains. This gene encodes a secreted protein that has low sequence similarity to the dickkopf-3 protein. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Oct 2010]

The c.629A>G (p.K210R) alteration is located in exon 5 (coding exon 5) of the DKKL1 gene. This alteration results from a A to G substitution at nucleotide position 629, causing the lysine (K) at amino acid position 210 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
