Xeroderma Pigmentosum (XP)

Xeroderma pigmentosum (XP) is a rare genetic defect that causes acute sensitivity to ultra violet light, particularly sunlight. XP can result in blindness and deafness, blistering or freckling on minimum sun exposure, developmental disabilities, dwarfism and hypergonadism, increased skin and eye cancers, and mental retardation.
