Schere's Disease is a form of acute hepatic porphyria. Symptoms include severe anaemia, sterility, difficulty digesting most foods, and extreme sensitivity to sunlight. The sensitivity is so acute that direct exposure to sunlight can cause third-degree burns, or even kill. Sufferers maintain a youthful appearance, but often don't live past 50. The major proponent in awareness of Schere's Disease is the Schere Foundation, currently headed by Dr. Emily Schere, the ghoul of Dr. Harold Schere.
