rare genetic disorder causing skin inflammation and brittle hair
Netherton Syndrome is a rare genetic disorder characterized by chronic skin inflammation, a distinctive hair shaft abnormality called trichorrhexis invaginata (bamboo hair), and a predisposition to allergies and infections. It is caused by mutations in the SPINK5 gene, which affects the skin's barrier function, leading to symptoms like red, scaly skin and brittle hair.
