Diseases of metabolism Flashcards
Glycogen storage disease:
Glucose 6 phosphates is defective so that liver cannot release glucose into the blood
Von Gierke disease
name the disease that effects lysosomal glycogenolysis by a deficiency in acid maltase and is treatable by a synthetic enzyme infusion.
glycogen accumulates in lysosomes and disrupts function of muscle and liver
children die of heart failure
Pompe disease
name the glycogen metabolism disease that has a deficiency in glycogen synthase where patients cannot synthesize glycogen and therefore rely on glucose from diet, are ofter hypoglycemic and have muscle cramps
GSD-0
name the glycogen metabolism disease that is caused by a deficiency in glucose transferase, causing patients to have fewer, longer branches in glycogen, causes enlargement of liver and spleen and liver scarring. very serious, usually death by age 5
Anderson Disease
name the disease that is caused by a deficiency in muscle glycogen phosphorylase.
- myoglobinuria
- weakness and muscle cramps
McArdle Disease
name the disease that is caused by deficiency in liver glycogen phosphorylase that causes hypoglycemia and hepatomegaly
Hers Disease
name the disease that is caused by a deficiency in A-Smase which breaks down sphingomyelin in lysosomes.
sphingomyelin accumulates in cells of liver, spleen, CNS
Leads to enlargement of liver, and spleen and neurological damage
Niemann - Pick Disease
name the condition of elevated levels of cholesterol in membrane of RBCs which decreasing fluidity and flexibility causing them to break with traveling thru spleen capillaries
Spur Cell Anemia
name the condition that is marked by thick mucus secretions in the lungs that commonly get infected. This is all due to deficiency in a Cl- channels in lung epithelial cells
Cystic Fibrosis
Name the condition that has a defect in the transport of cystine resulting in cystine crystals in the kidney
Cystinuria
name the disease that is caused by a defect in transporter for non-polar amino acids, primarily in the kidney and intestines.. this leads to a deficiency in tryptophan which makes serotonin. symptoms include cerebellar ataxia (lack of muscle movement)
Hartnup Disease
name the disease in the purine salvage pathway that has the defective enzyme HGPRT which causes an overproduction of uric acid
patients could have gout, urate kidney stones, poor muscle control and mental retardation and mutilation
Lesch Nahyn Syndrome
name the enzyme that is involved in pyrimidine synthesis that causes orotic acuduria by a build up of orotate
ump synthase
name the condition involved in purine degradation that is caused by deficiency in the enzyme adenosine deaminase (ADA)
SCID
name the condition involved in purine degradation that is caused by excess activity of the enzyme adenosine deaminase (ADA)
hemolytic anemia
