📋Overview
Xeroderma pigmentosum (XP) is a rare inherited disorder characterized by extreme sensitivity to ultraviolet (UV) light due to defective DNA repair mechanisms. It is caused by mutations in genes responsible for nucleotide excision repair, leading to an inability to correct UV-induced DNA damage. This results in early onset of severe sunburns, freckling, pigmentation changes, and a markedly increased risk of skin cancers. XP is the modern and preferred term for this condition.
