    Abstract

    Hailey-Hailey disease (HHD) is a rare autosomal dominant disorder characterized by recurrent skin lesions predominantly involving the body folds. It is caused by heterozygous mutations in the ATP2C1 gene, encoding the human secretory pathway Ca2+/Mn2+-ATPase protein 1 (hSPCA1). In this report we describe the molecular studies performed in eight HHD cases from Italy that led us to identify six different mutations scattered through the ATP2C1 gene in seven of eight cases. Four of the detected mutations were novel. Our results confirm the high allelic heterogeneity of the ATP2C1 gene and support the notion that HHD is a genetically homogeneous disorder. Furthermore, we created a table summarizing all previously reported ATP2C1 mutations, adapting the nomenclature, if needed, according to the guidelines of the Human Genome Variation Society.
