Hereditary fructose intolerance (HFI) is a rare metabolic disorder caused by aldolase B deficiency. Molecular analysis identified the common A149P mutation in a Portuguese child, aiding diagnosis for at-risk families.

Area of Science:

  • Biochemistry
  • Genetics
  • Pediatric Medicine

Background:

  • Hereditary fructose intolerance (HFI) is a rare autosomal recessive metabolic disorder.
  • It stems from a deficiency in the liver, kidney, and intestine enzyme aldolase B (fructose-biphosphate aldolase).

Observation:

  • A Portuguese child presented with symptoms suggestive of HFI.
  • Molecular analysis was performed to investigate the genetic basis of the condition.

Findings:

  • The study identified the A149P mutation in the aldolase B gene in the Portuguese child.
  • This is the same mutation previously found in most European HFI patients.

Implications:

  • This case represents the first molecularly confirmed HFI diagnosis in a Portuguese child.

  • Molecular studies are crucial for diagnosing HFI risk patients and their families, enabling early intervention and genetic counseling.
