Laminopathies are genetic disorders caused by mutations in the LMNA gene. This review explores the link between specific gene mutations and disease presentation, alongside new animal models and mechanisms.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cell Biology

Context:

  • Laminopathies represent a group of genetic disorders characterized by diverse clinical manifestations and tissue-specific pathologies.
  • These diseases primarily arise from mutations in the LMNA gene, which codes for nuclear lamin A/C proteins.
  • Over nine distinct human diseases have been linked to LMNA mutations, often presenting with seemingly unrelated phenotypes.

Purpose:

  • To provide a comprehensive overview of the genotype-phenotype relationship in laminopathies.
  • To summarize recent advancements in the development and application of animal models for studying these diseases.
  • To elucidate the underlying pathogenic mechanisms contributing to laminopathy development.

Summary:

  • This review details the intricate connection between specific mutations within the LMNA gene and the resulting clinical phenotypes observed in laminopathies.
