This is a simpler database than OMIM. It lists and describes about 1000 traits including common monogenic disorders and is curated by the United States’ National Library of Medicine. It also has a useful educational handbook.
This site catalogues the common genetic variants found in human genomes and how these are linked on chromosomes. Chromosome regions with linked variants are known as haplotypes and maps of haplotypes in populations with African or Asian or European Ancestries have been determined by this international consortium.
This is the website for a health policy think-tank with a focus on how genetic medicine and new technologies can have an impact on public health. It presents resources for education, research, and policy development in the field of human genomics.
