XP genes

XP genes are responsible for protecting the body from damage caused by ultraviolet (UV) rays from the sun. They produce proteins involved in repairing DNA that has been harmed by UV exposure. When these genes function properly, they help prevent skin cells from accumulating mutations that can lead to skin cancers. However, in individuals with xeroderma pigmentosum (XP), these genes are defective, meaning DNA repair is inefficient. This increases the risk of severe sunburns, early skin aging, and skin cancers. Essentially, XP genes are part of the body's natural system for fixing UV-induced DNA damage, maintaining skin health and reducing cancer risk.
