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]

ENSG00000268686 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=3.1620264E-4).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.44 is higher than 0.05.
