Question 6

Which of the following conditions is an extreme form of hypoalphalipoproteinemia? a) Familial hypercholesterolemia b) Dysbetalipoprotenemia c) Tangier disease d) Hypertriglyceridemia

Answer 6

C

Question 7

What is the typical HDL-C concentration range in individuals with Tangier disease? a) 20-30 mg/dL b) 10-20 mg/dL c) 5-10 mg/dL d) 1-2 mg/dL

Answer 7

D

Question 8

Answer 8

Hypoalphalipoproteinemia is characterized by low levels of HDL cholesterol, also known as the “good” cholesterol. HDL helps remove excess cholesterol from the bloodstream. Low levels of HDL cholesterol can increase the risk of heart disease.

Question 9

Answer 9

Hypobetalipoproteinemia is characterized by low levels of LDL cholesterol, also known as the “bad” cholesterol. LDL cholesterol contributes to plaque buildup in the arteries, which can lead to heart disease. Low levels of LDL cholesterol are generally considered beneficial for cardiovascular health.

Question 10

Characterized by low levels of HDL cholesterol.

Answer 10

hypoalphalipoproteinemia

Question 11

Characterized by low levels of LDL cholesterol.

Answer 11

hypobetalipoproteinemia

Question 12

Associated with an increased risk of cardiovascular disease.

Answer 12

hypoalphalipoproteinemia

Question 13

Associated with a decreased risk of cardiovascular disease.

Answer 13

hypobetalipoproteinemia

Question 14

Often caused by mutations in the ABCA1 gene.

Answer 14

hypoalphalipoproteinemia

Question 15

Often caused by mutations in the APOB gene.

Answer 15

hypobetalipoproteinemia

Question 16

Tangier disease is an extreme form of this condition.

Answer 16

hypoalphalipoproteinemia
