HDL > 90 mg/dL Research Studies

Hyperalphalipoproteinemia Research Study - Diagnosis and Followup Protocol

If you have hyperalphalipoproteinemia with high density lipoprotein (HDL) >90 mg/dL, you are invited to participate in a study in an attempt to diagnose and follow your disorder. There are several known causes of high HDL and they include Cholesteryl Ester Transfer Protein deficiency (CETP deficiency) and Hepatic Lipase deficiency. However, many causes of high HDL are unknown and are currently being investigated. 

Eligible persons will undergo a comprehensive evaluation at no cost to you. All patients will remain under the care of their own physician who will receive results of the laboratory and diagnostic tests. In many cases, you will be invited back for yearly evaluations related to other studies. There is no cost to you for travel and for some of your medications.
