Xeroderma pigmentosum is an autosomal recessive disorder that results in the skin’s inability to repair damage caused by ultraviolet light. This results in symptoms such as severe sunburn, development of excessive freckles, cry skin, blisters and corneal ulcerations. One of the most common causes of death in people with Xeroderma pigmentosum is skin cancer - specifically metastatic melanoma and squamous cell carcinoma.
Hi Cassie, with mundane medicine being forbidden in the Shadowhunter world I'm wondering what would happen to those with rare genetic diseases. My daughter has one called cystinosis and requires a lot of medicine to keep her healthy. Would a genetic disorder be something that the Silent Brothers could heal? Or would her family need to become mundane so she could live? Are Shadowhunters even susceptible to genetic disorders? Thank you for your time :)
