Abstract

Punctate palmoplantar keratoderma type I (PPPK1; also known as Buschke-Fischer-Brauer type; OMIM 148600) is an autosomal dominant disorder of keratinization, characterised by multiple hyperkeratotic lesions on palms and soles that usually start in early adolescence but may also start later in life (1). Lesions increase in size and number with advancing age and may coalesce over pressure points to form larger plaques. Recently, two consecutive studies identified the causative gene for PPPK1 as AAGAB (2, 3), located on chromosome 15q23, a locus to which the causal gene for PPPK1 was previously mapped (4).
