Q

Phenylketonuria

A

4
Q

Tyrosinemia Type I

A

When Fumarylacetoacetate Hydrolase accumulates it gets reduced to Succinylacetoacete (diagnostic) which leads to kidney and liver damage.

5
Q

Tyrosinemia Type II

A

Treatment of Type II just stops production of homogentisiic acid

A
27
Q

Non-Ketotic Hyperglycinemia

A
28
Q

Hyperglycemia may also result from which one of the following?

PKU

B12 Deficiency

Vitamin C Deficiency

B1 Deficeincy

Using an MAO inhibitor
