Abstract

Hailey-Hailey disease (HHD) is a rare autosomal dominant genodermatosis. It is characterized clinically by recurrent erosions, blisters and erythematous plaques at the sites of friction and intertriginous areas. The pathogenic gene of HHD was reported to be the ATPase calcium-transporting type 2C member 1 gene (). In this study, genomic DNA polymerase chain reaction (PCR) and direct sequencing of were performed from 3 Chinese pedigrees and 4 sporadic cases of HHD. We detected 3 heterozygous mutations, including 2 novel mutations (c.1673_1674insGTTG and c.2225A>G) and 1 recurrent nonsense mutation (c.1402C>T; NM_014382.4). The gene was also screened in the asymptomatic members of pedigrees. Our results would further expand the mutation spectrum of the gene and be helpful in the genetic counseling of patients with HHD.
