Punctate palmoplantar keratoderma type 1 (PPPK1) is a rare autosomal dominant inherited skin disease, characterized by multiple hyperkeratotic lesions on the palms and soles. The causative gene for PPPK1 has been identified as AAGAB, which encodes α- and γ-adaptin-binding protein p34. We describe the clinical features in three unrelated families with PPPK1, and report three recurrent causative mutations in AAGAB.
1型点状掌跖角化病（PPPK1）是一种罕见的常染色体显性遗传性皮肤病，其特征为手掌和脚底出现多个角化过度性损害。已确定PPPK1的致病基因为AAGAB，它编码α和γ衔接蛋白结合蛋白p34。我们描述了三个不相关的PPPK1家系的临床特征，并报告了AAGAB中的三个复发性致病突变。
