The causes of the onset of the disease in older people are most often associated with taking medications, manifested as a side effect of the therapy being taken, cancer, and in children, both an acquired character and a genetic predisposition are responsible for the manifestation of linear IgA-dependent bullous dermatosis. The diagnosis can be confirmed by histological and immunofluorescence analysis.
