SLC26A3 and Diarrhea: Congenital chloride diarrhea, a rare autosomal recessive disorder, can result from any of over 100 mutations of the solute carrier family 26 member 3 (SLC26A3) gene, which encodes an intestinal Cl−/HCO3−, Na+‐independent exchanger (Hoglund et al., 1998; Konishi et al., 2019; Makela, Kere, Holmberg, & Hoglund, 2002; Wedenoja et al., 2011).
