Researchers have identified over a thousand quantitative trait loci (QTLs) in rats linked to complex human diseases. The next step is to pinpoint the specific genes and DNA variations responsible, utilizing new genetic technologies.

Area of Science:

  • Genetics
  • Genomics
  • Human Disease Research

Background:

  • Over a thousand quantitative trait loci (QTLs) associated with complex human diseases have been identified in rat models over several decades.
  • Rat inbred lines have been instrumental in mapping genetic regions linked to various disease aspects.

Purpose of the Study:

  • To transition from QTL identification to the causal confirmation of specific polymorphisms and genes underlying complex human diseases in rats.
  • To leverage recent advancements in genetic technologies for precise gene and variant discovery in rat models.

Main Methods:

  • Utilizing a comprehensive collection of quantitative trait loci (QTLs) data from diverse rat inbred lines.
  • Employing single nucleotide polymorphism (SNP)-based genetic markers for high-resolution genetic mapping.
