Answer 1

The symptoms of xeroderma pigmentosum, or XP, usually appear in infancy. They can range from extreme sunburn after a few minutes of exposure to UV rays, to the reddening of the white of the eyes if no sun protection is worn. Most patients with XP develop skin or eye cancer multiple times in their lifetime. Around half of the children diagnosed with XP will develop skin cancer by their 10th birthday.
