Immunogenetics Immunogenetics Immunogenetics or immungenetics is the branch of medical genetics that explores the relationship between the immune system and genetics. Autoimmune diseases, such as type 1 diabetes, are complex genetic traits which result from defects in the immune system. Identification of genes defining the immune defects may identify new target genes for therapeutic approaches. Alternatively, genetic variations can also help to define the immunological pathway leading to disease. Its origin is usually attributed to Edward Jenner, who discovered in 1796 that cowpox, or vaccinia, induced protection against human smallpox. It took two centuries before the World Health Organization announced in
Caitlyn Jenner the pole vault, when Jenner took the lead, and javelin. By that point, victory was virtually assured, but it remained to be seen by how much Jenner would improve the record. In the final event—the 1500 meters, which was seen live on national television—Jenner looked content to finish the long competition. Jenner sprinted the last lap, making up a 50-meter deficit and nearly catching the event favorite, Soviet Leonid Litvinenko, who was already well out of contention for the gold medal, but whose personal best had been eight seconds better than Jenner's personal best before the race. Jenner set a
