[Mutation analysis of ATP2C1 gene in a Chinese family with Hailey-Hailey disease].

OBJECTIVE: To study a Chinese pedigree with Hailey-Hailey disease (HHD) and identify the ATP2C1 gene mutation in this family. METHODS: All exons of the ATP2C1 gene were analyzed with polymerase chain reaction and DNA sequencing in all patients of this family and 80 unrelated population-matched controls. RESULTS: We identified a nonsense mutation 163C to T, resulting in a premature termination codon in ATP2C1 gene. The mutation was not found in normal individuals of the family and controls. CONCLUSION: The mutation can affect the result of transcription and translation of ATP2C1 gene, and it is firstly reported in the Chinese pedigree with HHD.
