Question

A 12-year-old male is brought to his primary care physician. His parents are concerned with his recent decline in school work due to persistent blurred vision. On physical exam, planar xanthomas are noted and laboratory testing reveals extremely low plasma HDL. This presentation would be consistent with a loss of which of the following apoproteins?
A. ApoB 100
B. ApoA
C. ApoB 48
D. ApoE

Answer 1

Answer:

B. ApoA

Explanation:

Apolipoprotein A is a protein carried in HDL ("good") cholesterol. It helps start the process for HDL to remove bad types of cholesterol from your body. In this way, apolipoprotein A can help to lower your risk for cardiovascular disease.

Therefore, loss in ApoA will result in increased "bad" cholesterol since HDL process is not started, this will result in symptoms such as blurred vision
