Genetic hyperchylomicronemia is a rare autosomal recessive disorder of lipoprotein metabolism estimated to affect approximately one per million individuals. We report a case with a rare mutation identified. It’s a genetic chylomicronemia in a Moroccan newborn baby, with massive hypertriglyceridemia and clinical signs of acute pancreatitis. She was a newborn female, first-degree of consanguineous parents. She was hospitalized for hypertriglyceridemia, complicated by acute pancreatitis; serum was noted to be milky. The genetic study found a mutation of the Lipoprotein Lipase (LPL) gene: homozygous pathogenic variant c.1019-3C > A.
She enjoyed good health, developed well and the triglyceride was maintained at a concentration of
