Summary
Mucopolysaccharidoses are rare genetic lysosomal storage diseases diagnosed via enzyme defects and glycosaminoglycan excretion. This review details pre- and postnatal morphological changes across various tissues, aiding diagnosis and understanding pathogenesis.
Area of Science:
- Biochemistry
- Genetics
- Pathology
Context:
- Mucopolysaccharidoses (MPS) are inherited lysosomal storage diseases affecting 1 in 10,000–16,000 births.
- Diagnosis relies on biochemical enzyme defect verification and urinary glycosaminoglycan analysis.
- Morphological studies are crucial for genetic counseling and understanding disease pathogenesis.
Purpose:
- To provide an updated review of light and electron microscopic findings in various MPS types.
- To correlate morphological changes with clinical symptomatology.
- To highlight pre- and postnatal diagnostic features and pathogenetic mechanisms.
Summary:
- Lysosomal storage affects most organs in MPS, with quantitative and qualitative variations.
- These variations contribute to diverse clinical presentations.
- The review details specific tissue alterations and diagnostic criteria.
Impact:
- Enhances understanding of MPS pathogenesis through detailed morphological analysis.
- Improves pre- and postnatal diagnostic accuracy.
- Provides a foundation for genetic counseling and future therapeutic strategies.
