Area of Science:

  • Genomics
  • Human Genetics

Context:

  • Human genome programs have historically focused on gene mapping for disease gene identification and sequencing.
  • Established gene mapping goals have been met with over 7,000 microsatellite markers providing high-resolution mapping capabilities.

Purpose:

  • To review the progress in human genome mapping and discuss its implications for future large-scale sequencing studies.
  • To highlight the utility of radiation hybrids in gene mapping and their role in advancing genome research.

Summary:

  • Current microsatellite marker density allows localization of monogenic disease genes within 1-2 million base pairs.
  • Physical maps, utilizing yeast artificial chromosomes (YACs), now cover over 90% of the genome, though YAC rearrangements limit direct sequencing applications.
  • Radiation hybrids offer a valuable tool for integrating genes into existing maps, with over 15,000 gene tags successfully mapped by international collaborations.
