frontal fibrosing alopecia rs9258883 polymorphism HLA-B*07:02 allele rs1800440 polymorphism CYP1B1 gene FFA HLA-B CYP1B1

Studysummary In this study, researchers found that most patients with frontal fibrosing alopecia lacked the protective rs1800440 polymorphism in the CYP1B1 gene, suggesting its potential role in the development of this condition, while a significant number carried the rs9258883 polymorphism in HLA-B*07:02.
