When do signs of xeroderma pigmentosum appear?

Signs of xeroderma pigmentosum (XP) typically appear in early childhood, often before the age of 2. The most common initial symptom is increased sensitivity to sunlight, leading to sunburns, freckling, and skin lesions. As children with XP are exposed to UV rays, they may develop skin cancers at an unusually young age. Early diagnosis and protective measures are crucial to manage the condition and reduce the risk of skin damage.
