research Study of Human Leukocyte Antigen ( HLA ) in 13 cases of familial frontal fibrosing alopecia: CYP 21A2 gene p.V281L mutation from congenital adrenal hyperplasia linked to HLA class I haplotype HLA ‐ A*33:01 ; B*14:02; C*08:02 as a genetic marker
In this study, the CYP 21A2 gene p.V281L mutation was associated with an increased susceptibility to familial frontal fibrosing alopecia, suggesting an antigen-driven mechanism linked to certain human leukocyte antigen haplotypes.
