India's Rare Disease Breakthrough: XP's Genetic Eye Secrets Unlocked
3 Feb
Summary
- New genetic causes of severe eye damage in XP patients identified.
- Consanguineous marriages identified as major risk factor for XP.
- Early diagnosis and sun protection crucial to prevent irreversible vision loss.
In a significant advancement for rare disease research in India, physicians at the LVPEI have identified novel genetic factors contributing to severe eye damage in individuals with xeroderma pigmentosum (XP). This inherited disorder renders patients exceptionally sensitive to sunlight. The research, documented in the journal 'Cornea,' represents a pioneering effort within the Indian population to understand XP's ocular manifestations.
The study examined 23 XP patients, predominantly children and young adults, revealing that over a third experienced abnormal eye growths, some with cancerous potential. Dr. Sunita Chaurasia stressed the urgency of early diagnosis, genetic counseling, and comprehensive sun protection measures to avert irreversible vision loss. Severe photophobia and varying degrees of vision impairment were common among all participants.
