" /> Fructose intolerance, hereditary - CISMeF





Preferred Label : Fructose intolerance, hereditary;

Symbol : HFI;

CISMeF acronym : HFI;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Aldob deficiency; FRUCTOSEMIA; Fructose-1-phosphate aldolase deficiency; Aldolase b deficiency; Fructose-1,6-bisphosphate aldolase b deficiency;

Description : Fructose intolerance becomes apparent in infancy at the time of weaning, when fructose or sucrose is added to the diet. Clinical features include recurrent vomiting, abdominal pain, and hypoglycemia that may be fatal. Long-term exposure to fructose can result in liver failure, renal tubulopathy, and growth retardation. Older patients who survive infancy develop a natural avoidance of sweets and fruits. Ali et al. (1998) provided a detailed review of the biochemical, genetic, and molecular basis of aldolase B deficiency in hereditary fructose intolerance.;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the aldolase B, fructose-bisphosphate gene (ALDOB, 612724.0001);

Laboratory abnormalities : Hypoglycemia; Fructosemia; Hyperuricemia; Hypophosphatemia; Abnormal liver function tests; Fructose-1,6-bisphosphate aldolase B deficiency;

Prefixed ID : #229600;
