Fructose-1,6-Diphosphatase Deficiencies

   An autosomal recessive fructose metabolism disorder due to absent or deficient fructose-1,6-diphosphatase activity. Gluconeogenesis is impaired, resulting in accumulation of gluconeogenic precursors (e.g., amino acids, lactate, ketones) and manifested as hypoglycemia, ketosis, and lactic acidosis. Episodes in the newborn infant are often lethal. Later episodes are often brought on by fasting and febrile infections. As patients age through early childhood, tolerance to fasting improves and development becomes normal.

RELATED TERMS
--------------------------------------

Autosomal
"Pertaining to a chromosome that is not a sex chromosome; relating to any one of the chromosomes save the sex chromosomes. People normally have 22 pairs of autosomes (44 autosomes) in each cell together with two sex chromosomes (X and Y in the male and XX in the female). "

Fructose
Fruit sugar.

Metabolism
The chemical activity that occurs in cells, releasing energy from nutrients, or using energy to create other substances, such as proteins.

Fructose-1,6-diphosphatase
An enzyme that catalyzes the conversion of D-fructose 1,6-bisphosphate and water to D-fructose 6-phosphate and orthophosphate. EC 3.1.3.11.

Gluconeogenesis
The process by which GLUCOSE is formed from a non-carbohydrate source.

Hypoglycemia
Low levels of blood sugar.

Ketosis
A condition of having ketone bodies build up in body tissues and fluids. The signs of ketosis are nausea, vomiting, and stomach pain. Ketosis can lead to ketoacidosis.

Acidosis
An abnormal condition in the body in which excessive acid lowers the pH of the blood and body tissues.

Infant
A child under a year of age.

Fasting
Abstaining from all food.

Febrile
Caused by fever. Feverish.

Childhood
1. The time for a boy or girl from birth until he or she is an adult. 2. The more circumscribed period of time from infancy to the onset of puberty.

Tolerance
Diminished or absent capacity to make a specific response to an antigen, usually produced as a result of contact with that antigen under nonimmunizing conditions.

Development
The process of growth and differentiation.



SIMILAR TERMS
--------------------------------------

Fructans
Polysaccharides composed of D-fructose units.

Fructokinases
A class of enzymes that catalyzes the phosphorylation of fructose in the presence of ATP. EC 2.7.1.-.

Fructosamine
A term referring to the linking of blood sugar onto protein molecules in the bloodstream. The fructosamine value depends upon the average blood sugar level during the past three weeks. The fructosamine test could be viewed as complementary to the glycohemoglobin, as the two tests are different reflections of diabetes control: glycohemoglobin looks back approximately eight to twelve weeks, and the fructosamine test looks back about three weeks. |Note: the term fructosamine has nothing to do with the term fructose.

Fructose
Fruit sugar.

Prolonged fructose ingestion in infants leads ultimately to hepatic failure and death. Patients develop a strong distaste for sweet food, and avoid a chronic course of the disease by remaining on a fructose- and sucrose-free diet.
