As control, sera from normal volunteers (n = 52), patients with pemphigus vulgaris (n = 24), pemphigus foliaceus (n = 4) and bullous pemphigoid (n = 28) did not immunoprecipitate A2ML1-c-myc from transfected HEK 293T cells (representative samples are presented Figure 4B). The gene discussed is A2ML1; the disease is pemphigus foliaceus.
