What is NON RARE IN EUROPE: Familial hypobetalipoproteinemia?

Familial hypobetalipoproteinemia (FHBL) is an inherited condition where the body produces very low levels of certain fats and fat-carrying proteins in the blood — specifically a protein called apolipoprotein B (apoB) and a type of cholesterol called LDL ('bad cholesterol'). While low LDL might sound like a good thing, having levels that are too low can actually cause serious health problems over time. This condition is also sometimes called familial low LDL syndrome or apoB deficiency. The disease mainly affects the liver and the digestive system. Because the body cannot properly package and transport fats, fat-soluble vitamins like vitamin E, vitamin A, vitamin D, and vitamin K may not be absorbed well. This can lead to nerve damage, muscle weakness, and eye problems if left untreated. The liver may also accumulate fat, which can cause liver disease over time. Many people with a milder form of FHBL have no symptoms at all and are only diagnosed through routine blood tests. Others, especially those with more severe forms, may develop significant neurological and liver problems. Treatment focuses on high-dose vitamin supplements — especially vitamin E — to prevent nerve and eye damage. With early diagnosis and proper supplementation, many people can live relatively normal lives.

Key symptoms:

Very low LDL ('bad') cholesterol levels on blood testsFat buildup in the liver (fatty liver disease)Difficulty absorbing fat-soluble vitamins (A, D, E, K)Nerve damage causing numbness, tingling, or balance problemsMuscle weaknessVision problems, including night blindness or retinal damageFatigue and low energyDiarrhea or fatty, greasy stoolsAbdominal discomfort or bloatingBleeding problems due to low vitamin K (in severe cases)Bone thinning (osteoporosis) due to low vitamin D
