Acute pancreatitis as a key to diagnosis of hyperhomocysteinemia in a 12-year-old boy caused by CBS gene mutation

A 12-year-old boy with a 3-week history of abdominal pain, was referred to our emergency room. The patient had been diagnosed with acute pancreatitis at another hospital before he came to see us. Notably after treatment, he went into remission, but relapsed after he started eating again, prompting the referral to our department.
