Xeroderma pigmentosum

MONDO:0019600

Xeroderma pigmentosum (XP) is a rare genodermatosis characterized by extreme sensitivity to ultraviolet (UV)-induced changes in the skin and eyes, and multiple skin cancers. It is subdivided into 8 complementation groups, according to the affected gene: classical XP (XPA to XPG) and XP variant (XPV).

Also known as: Kaposi dermatosis, Kaposi disease, XP, angioma pigmentosum atrophicum, atrophoderma pigmentosum, melanosis lenticularis progressiva, pigmented epitheliomatosis, xeroderma of Kaposi

Scientists track rare DNA repair diseases to learn how they progress

Knowledge-focused Recruiting now

This study is for people with rare DNA repair disorders like Cockayne syndrome, xeroderma pigmentosum, or trichothiodystrophy. Researchers will watch how symptoms like movement and balance change over time. No treatments are given—the goal is to better understand these conditions…
