#xeroderma_pigmentosum
#xeroderma_pigmentosum :-
A genetic disease that is characterized by such extraordinary sensitivity to sunlight that it results in the development of skin cancer at a very early age. Abbreviated XP.
Children with #XP can only play outdoors safely after #nightfall.
XP is due to #defective repair of damage done to #DNA by #ultraviolet (UV) light. Whereas normal persons can repair UV-induced damage by inserting new bases into the DNA, XP patients cannot.
A person with XP #develops severe #sunburn and eye irritation within minutes of exposure to sunlight.
Other features of XP include very dry skin (#xeroderma), #blisters on the skin, heavy freckling, and dark spots on the skin.
XP is #inherited in an #autosomal recessive manner. Defects in multiple genes have been identified that lead to XP. Avoiding UV light and using the highest level of #sunscreen possible when exposure cannot be avoided helps prevent #complications.
