CTNNB1 is a gene that engages in WNT/β-catenin signaling that regulates cell fate and apoptosis whose role in eosinophil accumulation in EA asthma via negative regulation of apoptosis was reported by several existing studies (Kwak et al. 2015, Koopmans and Gosens, 2018). Here, CTNNB1 is linked to Esophageal atresia.
