Genes affected

ZEB2 (HGNC:14881): (zinc finger E-box binding homeobox 2) The protein encoded by this gene is a member of the Zfh1 family of 2-handed zinc finger/homeodomain proteins. It is located in the nucleus and functions as a DNA-binding transcriptional repressor that interacts with activated SMADs. Mutations in this gene are associated with Hirschsprung disease/Mowat-Wilson syndrome. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Jan 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.69).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.522 is higher than 0.05.
