Summary
Peroxisome biogenesis disorders (PBD) and Adrenoleukodystrophy (ALD) involve genetic defects. Recent advancements include identifying responsible genes and creating animal models to study disease mechanisms and develop therapies.
Area of Science:
- Genetics and Molecular Biology
- Biochemistry
- Cell Biology
Context:
- Peroxisome biogenesis disorders (PBD) encompass Zellweger syndrome, neonatal adrenoleukodystrophy, and infantile Refsum disease, classified into ten complementation groups.
- Adrenoleukodystrophy (ALD) is a common peroxisomal disorder with significant phenotypic variability.
Purpose:
- To review the identification of pathogenic genes responsible for PBD and ALD.
- To discuss the genetic basis and mutation spectrum of ALD.
- To highlight the development and potential of animal models for PBD and ALD research.
Summary:
- Five pathogenic genes for PBD have been identified using model systems and homology searches.
- The ALD gene, encoding the ALDP transporter, has about 120 identified mutations with no clear genotype-phenotype correlation.
- Targeted mutation of PBD and ALD genes has yielded mouse models.
Impact:
- These mouse models are crucial for investigating PBD and ALD, particularly factors influencing phenotypic heterogeneity.
- Research using these models is expected to advance the development of novel therapeutic strategies for PBD and ALD.
- Understanding the genetic underpinnings and variability of these disorders is key to improving patient outcomes.
