Genes affected

WNT2 (HGNC:12780): (Wnt family member 2) This gene is a member of the WNT gene family. The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.24).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.325 is higher than 0.05.
