19
Q

Which glycogen storage diseases affect the muscle?

A

3, 5, 7

20
Q

What glycogen storage disease affects every organ?

A

Type II, Pompe’s disease

21
Q

What is the only glycogen storage disorder that leads to a decrease in glycogen?

A

Type 0- a defect in glycogen synthase

22
Q

What organ/s does glycogen synthase deficiency affect?

A

The liver

23
Q

What organ/s is affected by type I disease?

A

Liver and kidney

24
Q

What organ/s is affected by type II disease?

A

All organs

25
Q

What organ/s is affected by type III disease?

A

Muscle and liver

26
Q

What organ/s is affected by type IV disease?

A

Liver and spleen

27
Q

What organ/s is affected by type V disease?

A

Muscle

28
Q

What organ/s is affected by type VI disease?

A

Liver

29
Q

What organ/s is affected by type VII disease?

A

Muscle

30
Q

What organ/s is affected by type VIII disease?

A

Liver

31
Q

Which types lead to death, usually before age 2?

A

Type 2 and type 4

32
Q

What are the clinical features of type 0 glycogen storage disease?

A

Hypoglycemia, postprandial lactic acidemia, fasting ketosis

Problems associated with the fact that you can’t store glucose as glycogen, so you don’t have stores to pull from in the liver when you’re fasting

33
Q

What are the clinical features of type I glycogen storage disease?

A

Enlarged liver, failure to thrive, severe hypoglycemia, gouty arthritics,, hyperlipidemia, mental retardation, lactic acidosis

You can break down glycogen, but you can’t get it to a usable form (glucose)

34
Q

What are the clinical features associated with type II glycogen storage disease?

A

cardiorespiratory failure and death before age 2

35
Q

What are the clinical features associated with type III glycogen storage disease?

A

Like type 1, but milder.

You can only break down and use some of the glycogen

36
Q

What are the clinical features associated with type IV glycogen storage disease?

A

Liver failure –> death

37
Q

What are the clinical features associated with type V glycogen storage disease?

A

limited ability to perform exercise, due to painful cramps.

This affects muscle only- liver is still able to maintain normal blood glucose levels

38
Q

What are the clinical features associated with type VI glycogen storage disease?

A

Like 1, but milder

39
Q

What are the clinical features associated with type VII glycogen storage disorder?

A

Like 5.

Affects the muscle, therefore inability to use glycogen to produce ATP

40
Q

What are the clinical features associated with type VIII glycogen storage disorder?

A

Mild liver enlargement and mild hypoglycemia

Affects liver. Mild because phosphorylase b can be activated to phosphorylase a via allosteric regulation
