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]

Ambry Genetics

May 31, 2023

The c.529C>T (p.R177W) alteration is located in exon 5 (coding exon 5) of the DKKL1 gene. This alteration results from a C to T substitution at nucleotide position 529, causing the arginine (R) at amino acid position 177 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
