Hypobetalipoproteinemia is a disorder consisting of low levels of LDL cholesterol or apolipoprotein B, below the 5th percentile. The patient can have hypobetalipoproteinemia and simultaneously have high levels of HDL cholesterol. Notably, in people who do not have the genetic disorder hypobetalipoproteinemia, a low cholesterol level may be a marker for poor nutrition, wasting disease, cancer, hyperthyroidism, and liver disease. ==Causes== One form is thought to be caused by mutated apolipoprotein B. Another form is associated with microsomal triglyceride transfer protein which causes abetalipoproteinemia. A third form, chylomicron retention disease (CRD), is associated with SARA2. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Hypobetalipoproteinemia」の詳細全文を読む スポンサード リンク
