Genetic mutation turns people into real-life ‘vampires’
You can read it all in this article by Lizzy Parry that I saved in my Flipboard magazine.
The vampire stories There exists a gene mutation that blisters people’s skin when they go out in sunlight. This is caused by a condition, called erythropoietic protoporphyria (EPP) which prevents them from making heme/haem (the component of haemoglobin responsible for binding oxygen), which also makes them anemic and hence lethargic and pale.
In the olden days, they combatted the disease with drinking blood and only going out at night, which probably led to the vampire myth.
The disease still exists.
Vampires live on.
