The vampire 1 is the stuff of the great horror stories. However, a recent textbook by geneticist John Jenkins suggests that Bram Stoker’s legend of the vampire, Dracula, may have had its basis in a very real disease that prevents some people from getting rid of old red blood cells. In healthy people, red blood cells live only a short time and then are broken down by the body, which uses the chemical components 2 of old cells to make new ones. But in a hereditary 3 form of a disease known as “porphyria,” a missing enzyme 4 prevents the body from breaking down hemoglobin in old red blood cells. What happens instead is that the hemoglobin is only partially 5 broken down, the result being some very odd symptoms.
