Abstract

1. We extend the spectrum of SERPINA12 variants in palmoplantar keratodermas. 2. The recurrent variant c.970_971del, mainly prevalent in the East Asia population, was proved to be a founder variant. 3. Considerable SERPINA12-related palmoplantar keratoderma patients could be identified from autosomal recessive, non-mutilating, diffused palmoplantar keratoderma patients. 4. Other serpin family members or their co-effect may participate in the etiologies of underexplored hereditary palmoplantar keratodermas.
