He was a great-nephew of Burrill Bernard Crohn, for whom Crohn"s disease is named. Crohn had the "delta 32" mutation on the CCR5 receptor, a protein on the surface of white blood cells that is involved in the immune system and serves as an access route for many forms of Human Immunodeficiency Virus virus to enter and infect host cells. This mutation rendered him effectively immune to many forms of Human Immunodeficiency Virus.
Crohn committed suicide by a drug overdose on oxycodone and benzodiazepines at the age of 66.
