28 28 Reviewing George’s Symptoms Familial Hypercholesterolemia (FH) Fatty Deposit Coronary Artery: a heart artery Fatty Deposit Knees and Fingers Very high cholesterol in blood Waxy patches on the skin Chest pain and heart attacks at a young age Build up of fatty deposits on under skin and in arteries Learning Set 3 : Lesson 5 : Slide 28

29 George ’ s Family History Learning Set 3 : Lesson 5 : Slide 29 George Heart attack: 25y

30 30 Fatty Deposit Fatty Deposits In Coronary Artery Cross Section of Coronary Artery Fatty deposits made in artery wall, high blood pressure Arteries harden and narrow due to fat accumulation Blood flow is reduced Oxygen supply to heart reduced Can cause chest pain heart attack or death in severe cases Why George had a Heart Attack Normal Tear in artery wall Fatty deposits made in artery wall Narrowed artery blocked by blood clot Learning Set 3 : Lesson 5 : Slide 30

31 31 Estrogen Testosterone Bile Acids Cholesterol Cholesterol: Many Roles Learning Set 3 : Lesson 5 : Slide 31

32 32 nucleus cell inside cell outside cell Cholesterol in LDL LDL Receptor Plasma Membrane Takes LDL into cell cholesterol Low density lipoprotein (LDL) Receptor Learning Set 3 : Lesson 5 : Slide 32

33 LDL Receptor Learning Set 3 : Lesson 5 : Slide 33

34 34 Analyzing George ’ s LDL receptor A B C LDL receptor George ’ s LDL receptor Learning Set 3 : Lesson 5: Slide 34

35 35 Why did Rachel look at George ’ s DNA? One of George ’ s chromosomes, chromosome 19, had an arrow pointing at one spot on it. This arrow indicated something was different at this spot on chromosome 19. What does DNA have to do with the LDL receptor that causes FH disease? Learning Set 3 : Lesson 5 : Slide 35
