[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.
