Objective:
To investigate the mutations of ATP2C1 gene in Chinese patients with Hailey-Hailey disease (HHD).
Methods:
Genomic DNA was extracted from peripheral blood leukocytes. PCR and direct DNA sequencing were used to detect the mutations in all 27 exons of ATP2C1 gene in patients of two Chinese families and a sporadic patient with HHD.
Results:
Three mutations in ATP2C1 gene were found, including 1 nonsense mutation, 1 deletion/frameshift mutation and 1 missense mutation. All of them were novel mutations.
Conclusion:
All the three mutations could affect the transcription and translation, and further the function of protein encoded by ATP2C1 gene.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
