Area of Science:

  • Neuroimmunology
  • Human Genetics
  • Epidemiology

Background:

  • Multiple sclerosis (MS) is influenced by both genetic and environmental factors.
  • Understanding genetic susceptibility is crucial for unraveling MS pathogenesis.
  • Previous research has explored gene associations with MS in various populations.

Purpose of the Study:

  • To review reported associations between candidate genes and Japanese multiple sclerosis (MS).
  • To identify specific genetic markers linked to conventional and opticospinal MS subtypes in Japan.
  • To emphasize the importance of robust methodologies in genetic susceptibility studies for MS.

Main Methods:

  • Systematic review of case-control studies examining Japanese MS patients and controls.
  • Analysis of associations between specific human leukocyte antigen (HLA) alleles and MS.

  • Examination of polymorphisms in candidate genes including vitamin D receptor, estrogen receptor, CTLA-4, and osteopontin.

    • Main Results:

    • HLA-DRB1*1501 and HLA-DPB1*0501 alleles are associated with conventional MS and opticospinal MS, respectively.
    • Polymorphisms in vitamin D receptor, estrogen receptor, CTLA-4, and osteopontin genes show associations with conventional MS.
    • Evidence suggests specific genetic variations contribute to MS susceptibility in the Japanese population.

    Conclusions:

    • Genetic factors, particularly certain HLA alleles and other candidate genes, play a significant role in MS susceptibility among Japanese individuals.
    • Distinctions in genetic associations may exist between different MS subtypes (conventional vs. opticospinal MS).
    • Accurate case definition, data collection, and statistical analysis are essential for identifying MS susceptibility genes.
