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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 24, 2023The c.614G>A (p.R205H) alteration is located in exon 5 (coding exon 5) of the DKKL1 gene. This alteration results from a G to A substitution at nucleotide position 614, causing the arginine (R) at amino acid position 205 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
