|November 1, 1976
Summary
Familial type III hyperlipoproteinemia is rare in children, but early diagnosis is crucial. This study highlights two adolescents diagnosed with this condition, emphasizing the need for pediatric consideration in at-risk families.
Area of Science:
- Lipidology
- Genetics
- Pediatrics
Background:
- Familial type III hyperlipoproteinemia is typically diagnosed in adulthood.
- Pediatric cases are exceptionally rare, with only four previously reported.
- This disorder is characterized by abnormal very low-density lipoproteins (VLDL).
Observation:
- Two adolescents, a 16-year-old female (S.E.) and a 21-year-old male (C.H.), were diagnosed with type III hyperlipoproteinemia.
- Both presented with characteristic features, including palmar xanthomas in C.H. at age 16.
- Laboratory findings revealed beta-migrating VLDL (beta-VLDL) with a density less than 1.006 g/mL.
Findings:
- The probands had a strong family history of hyperlipoproteinemia, including type III and type IV.
- S.E.'s family had multiple affected members across generations.
- C.H.'s family also exhibited a history of type III and type IV hyperlipoproteinemia.
Implications:
- The findings underscore the importance of considering type III hyperlipoproteinemia in the pediatric population.
- Early diagnosis in children can facilitate timely management and potentially prevent long-term complications.
- Genetic screening and awareness in families with a history of hyperlipoproteinemia are vital for early detection in children.
