    Benign familial chronic pemphigus (Hailey-Hailey disease, HHD) is a rare hereditary condition characterized by development of blisters at sites of friction and in the intertriginous areas. Mutations in the ATP2C1 gene, which encodes the human secretory pathway calcium ATPase 1 (hSPCA1), have been identified as possible causative mutations. Studying Hungarian patients with HHD, we found two novel, distinct, heterozygous mutations. In a 65-year-old man with a 41-year history of severe recurrent symptoms, a single nucleotide insertion, 1085insA, was detected. In a patient whose symptoms were induced by environmental contact allergens, we found a nonsense mutation, Q506X, in exon 17. Our study further illustrates the diversity of mutational events in the pathogenesis of HHD.
