Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Principles of Pharmacogenetics: Types of Genetic Variants01:27

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu01:29

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Area of Science:

  • Genetics
  • Immunology
  • Neurology

Background:

  • Multiple sclerosis (MS) susceptibility has a known genetic component, with the HLA region identified as a major early risk factor.
  • Advances in genome-wide association studies (GWAS) have rapidly expanded the number of identified MS risk factors from one to over 50 in recent years.

Purpose of the Study:

  • To review the ongoing search for MS risk genes and present the latest findings.
  • To compare genetic risk factors for MS with those of other autoimmune and neurological diseases, as well as animal models.
  • To discuss the implications of these findings for understanding MS pathogenesis and identify current research challenges.

Main Methods:

  • Review of existing literature on genetic risk factors for multiple sclerosis.
  • Comparative analysis of genetic data from MS, other autoimmune diseases, neurological disorders, and animal models.
  • Discussion of genotype-phenotype correlations, functional mechanisms of risk variants, and the concept of missing heritability.

Main Results:

  • The number of identified genetic risk factors for MS has significantly increased due to GWAS.
  • Parallels and differences in genetic risk factors exist between MS and other diseases, offering insights into shared and distinct mechanisms.
  • Current challenges include establishing genotype-phenotype correlations, elucidating functional roles of risk variants, and addressing the missing heritability in MS.

Conclusions:

  • The genetic architecture of MS is complex, involving numerous risk loci beyond the HLA region.
  • Comparative genomics aids in unraveling the underlying biological pathways implicated in MS and related conditions.
  • Further research is needed to fully understand the functional impact of identified risk variants and explain the remaining heritability of MS.
