Definition
Lysosomal storage disease, but defect in golgi, actual deficiency is glucose aminoglycan phosphotransferase, mannose-6-phosphate tag isn't put onto lysosomal enzymes (acid hydrolyases), similar to hurler disease, but has characteristic inclusion bodes
Term
BeriBeri
Definition
Thiamin deficiency
Term
Anemia
Definition
B12 deficiency
Term
Uremia
Definition
blood urea nitrogen rises sharply in renal failure
Term
Essential fructosuria
Definition
results from a deficiency of fructokinase in the liver
Term
Hereditary fructose inolerance
Definition
deficiency of fructose-1-p aldolase of liver, kidney cortex, and small intestine
Term
Classic galactosemia
Definition
GALT, loss of uridylyltransferase
Term
Galactosemia
Definition
GALK, loss of galactokinase, can lead to blindiness, lactose intolerant
Term
Epipermase deficiency
Definition
GALE, 2 forms, one similar to tranferase deficiency
Term
glucose-6-phosphate dehydrogenase
Definition
No NADPH production in rbc. rbc can't handle additional oxidative stress from drugs or food items
Term
Neonatal jaundice
Definition
glucose-6-phospahte dehyrdogenase deficiency, bilirubin is a neurotoxin, treatment is bili-lights (460-490nm), converts bilirubin to lumirubin whichis water-soluble photoisomer and can't enter CNS and is excreted
Term
Hemolytic anemia
Definition
G6PD deficiency, induced by certain oxidative drugs, fava beans, or infections,
Term
Type 0 Glycogen storage disease
Definition
Deficiency of glycogen synthase, liver glycogenoses
Term
Von Gierke's
Definition
type I glycogen storage disease, glucose-6-phosphate
Term
Cori or Forbes
Definition
type III glycogen storage disease, glycogen debranching enzyme
Term
Hers
Definition
type VI glycogen storage disease, glycogen phosphorylase
Term
Type IX
Definition
glycogen storage disease, glycogen phosphorylase kinase (7 subtypes)
Term
Fanconi-Bickel
Definition
Type XI, glut-2-transporter, liver
Term
Andersen
Definition
Type IV, glycogen branching enzyme, live
Term
McArdle
Definition
Type V, glycogen phosphorylase, muscle
Term
Tarui
Definition
type V, PFK-1 muscle
Term
Kwashiorkor
Definition
deficiency of protein in a diet that is adequate in calories. Distended abdomen bc increase in interstitial fluid
Term
Cystic fibrosis
Definition
Genetic defect in the function of chloride channels present in the pancreatic secretory ducts, causes inspissations of pancreatic exocrine secretions. Treated with supplementation of pancreatic enzymes wiht meals
Term
Cystinuira
Definition
Genetic defect in transport system responsible for transport of cystine and the basic amino acids, lysine, arginine, and orithine. Causes kidney stones bc of insolubility of cystine
Term
Hartnup
Definition
Genetic defect in the transport of neutral amino acids across both intestinal and renal epithelial cells
Term
Schizophrenia and biopolar disease
Definition
Altered transport of tyrosine and tryptophan, which are precursors of dopamine and serotonin
Term
Uremia
Definition
BUN (blood urea nitrogen), rises sharply with renal failure
Term
Hyperammonemia
Definition
Plasma urea levels are higher which leads to greater transfer of urea from the blood into the intestine, making urease more active. Neomycin reduces number of bacteria. Affects CNS. Not from arginiase deficiency, but other urea cycle deficiencies. Treat with sodium benzoate, phenyl acetate, arginine
Term
Alkaptonuria
Definition
darkening of urine, deficient catabolism of phenylalanine and tyrosine
Term
Cysteinuria
Definition
mutation of renal amino acid transporter of dibasic amino acids such as cysteine
Term
Glycine Encephalopathy
Definition
caused by mutations in glycine enzymes of the mitochondria (P, T, or H enzyme)
Term
Histidinemia
Definition
histidine-ammonia lyase deficiency, considered a benign disorder
Term
Homocystinuria
Definition
Cystathionine B-synthase deficiency, dislocation of lenses or thromboembolic events or osteoporosis or mental retardation, can treat with pyroxidine or limit methionine. At least 7 causes of this disease
Term
Hyperlysinemia
Definition
a-aminoadipic semialdehyde synthase deficiency (enxyme catalyzes 2 steps in lysine degradation)
Term
Maple Syrup Urine Disease
Definition
branched-chain a-keto acid dehydrogenase (BCKD) deficiency, urnine smells like burnt sugar
Term
Methymalonic Aciduria
Definition
Methylmalonyl-CoA Mutase (MUT) deficiency, defects possible in Vit B12 metabolism, but don’t respond to B12 supplementation, wide clinical spectrum
Term
Phenylketonuria
Definition
phenylalanine hydroxylase deficiency, phenylalanine accumulates bc cant be converted to tyrosine
Term
Tyrosinemia
Definition
fumarylacetoacetase deficiency, accumulation of tyrosine succinylacetone
Term
Tyrosinemia Type II
Definition
tyrosine transaminase deficiency
Term
Tyrosinemia Type III
Definition
4-hydroxyphenylpyruvate dioxygenase deficiency
Term
Hartnups disease
Definition
mutations in SLC6A19 gene, not in US
Term
