Identification and functional characterization of a novel heterozygous missense variant in the LPL associated with recurrent hypertriglyceridemia‐induced acute pancreatitis in pregnancy

Acute pancreatitis in pregnancy (APIP) is a life‐threatening disease for both mother and fetus. To date, only three patients with recurrent hypertriglyceridemia‐induced APIP (HTG‐APIP) have been reported to carry rare variants in the lipoprotein lipase (LPL) gene, which encodes the key enzyme responsible for triglyceride (TG) metabolism. Coincidently, all three patients harbored LPL variants on both alleles and presented with complete or severe LPL deficiency.
