Diarrhea-13 (DIAR13) is characterized by neonatal onset of recurrent vomiting and chronic watery diarrhea, resulting in severe failure to thrive. Supportive treatment includes medium-chain triglyceride (MCT)-based formula and/or total parenteral nutrition (TPN), and symptoms resolve after the age of 18 months (Al-Thihli et al., 2021).
