A novel missense mutation of the ATP2C1 gene in a Chinese patient with Hailey-Hailey disease
Benign familial chronic pemphigus (Hailey-Hailey disease, HHD; M1M 169600) is a rare autosomal dominant hereditary disorder characterized by pruritic vesicles, painful erosions and scaly erythematous plaques at the sites of friction and flexures. Mutations in ATP2C1, which encoding the human secretory pathway Ca2+/Mn2+-ATPase protein 1 (hSPCA1), have been identified as the pathogenic gene of HHD. We found a novel, distinct, heterozygous mutation during study of a Chinese patient with HHD. We identified a C -> T transition at nucleotide 1235 (p.Thr352IIe), in exon 13 of ATP2C1. This observation would be useful for genetic counseling and prenatal diagnosis for affected families and in expanding the repertoire of ATP2C1 mutations underlying HHD. (C) 2011 Elsevier Inc.
