Peroxisomal disorders are genetic diseases impairing cellular metabolism, with Zellweger syndrome as a key example. This overview details their clinical, biochemical, and molecular aspects, focusing on neonatal presentation.

Area of Science:

  • Cell Biology
  • Genetics
  • Biochemistry

Background:

  • Peroxisomes are vital organelles for cellular metabolism.
  • Genetic defects in peroxisomal function lead to severe diseases.
  • Zellweger syndrome is a prototype peroxisomal disorder.

Purpose of the Study:

  • To provide an overview of peroxisomal disorders.
  • To detail their clinical, biochemical, and molecular characteristics.
  • To emphasize the clinical presentation in neonates.

Main Methods:

  • Literature review of peroxisomal disorders.
  • Analysis of clinical manifestations.
  • Examination of biochemical and molecular data.

Main Results:

  • Peroxisomal disorders present with diverse symptoms affecting multiple organs.
  • Zellweger syndrome involves dysmorphies, neurological defects, and liver dysfunction.
  • Other disorders show variable organ involvement and severity.

Conclusions:

  • Peroxisomal disorders represent a significant group of genetic diseases.
  • Understanding these disorders is crucial for diagnosis and management, especially in neonates.
  • Further research into peroxisomal function and disease mechanisms is warranted.
