Reviewing George’s Symptoms Familial Hypercholesterolemia (FH) • 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 Knees and Fingers Coronary Artery: a heart artery Fatty Deposit Fatty Deposit Learning Set 3 : Lesson 5 : Slide 28
George Heart attack: 25y George’s Family History Learning Set 3 : Lesson 5 : Slide 29
Why George had a Heart Attack Cross Section of Coronary Artery Fatty Deposits In Coronary Artery Tear in artery wall Normal Fatty Deposit Fatty deposits made in artery wall Narrowed artery blocked by blood clot • 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 Learning Set 3 : Lesson 5 : Slide 30

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
