LIPC

At least 10 mutations in the LIPC gene have been found to cause hepatic lipase deficiency. This condition leads to abnormal levels of various fats (lipids) in the bloodstream, although it is unclear whether these changes impact the risk of developing heart disease. The LIPC gene mutations that cause this condition change single protein building blocks (amino acids) in the hepatic lipase enzyme. These mutations prevent the enzyme's release from the liver or decrease its activity in the bloodstream. As a result, VLDLs and IDLs are not efficiently converted into LDLs, and HDLs carrying cholesterol and triglycerides remain in the bloodstream. It is unclear what effect this change in fat levels has on people with hepatic lipase deficiency, as some affected people develop an accumulation of fatty deposits on the artery walls (atherosclerosis) and heart disease in mid-adulthood, while others do not.
