|June 1, 1985
Summary
Biotinidase deficiency can cause biotin deficiency symptoms by 3 months. Early diagnosis via cord blood and biotin treatment preserved vision, hearing, and development in an infant.
Area of Science:
- Biochemistry
- Genetics
- Pediatrics
Background:
- Biotinidase deficiency is an inherited metabolic disorder.
- It leads to the body's inability to recycle biotin, a vital vitamin.
- Untreated, it causes symptoms of biotin deficiency.
Observation:
- A case study of an infant diagnosed with biotinidase deficiency via newborn screening (cord blood).
Findings:
- The infant received biotin supplementation presymptomatically.
- Vision and hearing remained normal.
- Physical and mental development were age-appropriate at 14 months.
Implications:
- Newborn screening for biotinidase deficiency enables early intervention.
- Presymptomatic treatment with biotin can prevent severe neurological damage.
- This highlights the importance of timely diagnosis and treatment for metabolic disorders.
