Multiple sclerosis (MS) is a complex neurological disease influenced by genetics and environment. This review explores how gene variations impact MS disease course and severity, contributing to its varied presentation.

Area of Science:

  • Neuroimmunology
  • Genetics
  • Neurology

Background:

  • Multiple sclerosis (MS) is an inflammatory demyelinating central nervous system disease.
  • Its etiology is multifactorial, involving genetic and environmental influences.
  • MS exhibits significant clinical heterogeneity in phenotype and severity.

Purpose of the Study:

  • To discuss recent findings on genetic factors influencing MS.
  • To explore theories on genotype-phenotype interactions in MS.
  • To understand the modifying role of genes in MS course and severity.

Main Methods:

  • Review of recent scientific studies and theories.
  • Analysis of genotype-phenotype interactions in multiple sclerosis.
  • Discussion of genetic and environmental factors in MS pathogenesis.

Main Results:

  • Genetic factors play a significant role in the multifactorial etiology of MS.
  • Gene variations contribute to the wide phenotypic variability and severity of MS.
  • Understanding genotype-phenotype interactions is key to explaining clinical heterogeneity.

Conclusions:

  • Genetic and environmental factors interplay to shape the course and severity of multiple sclerosis.
  • Further research into gene-environment interactions is crucial for understanding MS.
  • Genotype-phenotype correlations offer insights into MS clinical heterogeneity.
