Area of Science:

  • Genetics
  • Genomics
  • Human Disease Genetics

Background:

  • Monogenic diseases have extreme phenotypes, but polygenic disorders represent a greater public health burden.
  • Common polygenic diseases such as diabetes, hypertension, and multiple sclerosis affect large populations and incur substantial healthcare costs.
  • Current knowledge of the genetic basis for common polygenic diseases is limited.

Purpose of the Study:

  • To highlight the growing importance of polygenic disorders in overall genetic ill health.
  • To introduce whole genome screening as a significant advancement for studying polygenic diseases.
  • To document the historical progression of whole genome screening in human polygenic diseases.

Main Methods:

  • Whole genome screening was applied to polygenic diseases.
  • The study references the first genome screen in insulin-dependent diabetes mellitus (IDDM) in 1994.
  • Subsequent whole genome screening efforts in various polygenic diseases are noted.

Main Results:

  • Whole genome screening has emerged as a key technology for investigating the genetic underpinnings of common diseases.
  • The application of genome screening has expanded to include a range of polygenic conditions.
  • This approach has the potential to significantly improve our understanding of complex genetic diseases.

Conclusions:

  • Polygenic disorders are a major source of genetic disease burden, necessitating advanced research tools.
  • Whole genome screening represents a technological leap forward in the genetic analysis of common, complex diseases.
  • The continued application of whole genome screening is expected to enhance our knowledge of the genetic architecture of prevalent conditions like diabetes, multiple sclerosis, and others.
