Familial hypertriglyceridemia is caused by a genetic defect, which is passed on in an autosomal dominant fashion. This means that if you get a bad copy of the gene from just one of your parents, you will have the condition. Some people with this condition also have high levels of very low density lipoprotein (VLDL). The reason for the rise in triglycerides and VLDL is not understood. Familial hypertriglyceridemia does not usually become noticeable until puberty or early adulthood. Obesity, hyperglycemia (high blood glucose levels), and high levels of insulin are frequently associated with this condition and make cause even higher triglyceride levels. Familial hypertriglyceridemia occurs in about 1 in 500 individuals in the United States. Risk factors are a family history of hypertriglyceridemia or a family history of heart disease before the age of 50. |
