Darier's disease (DD) is an autosomal dominant genodermatosis characterized by epidermal acantholysis and dyskeratosis. We have performed genetic linkage studies in 10 families with DD (34 affected) by analyzing 14 polymorphic microsatellite markers. Our results confirm recent reports mapping the DD gene to chromosome 12q23-q24.1. Haplotype analysis of recombinant chromosomes in our families, along with previously reported data, narrow the location of the DD gene to a 5 cM interval flanked by the loci D12S354 and D12S84/D12S105. This localization allowed exclusion of two known genes, PLA2A and PAH, as candidate loci for DD. Three other gene loci (PPP1C, PMCH, PMCA1), mapping in 12q21-q24, remain potential candidates.

Aims: Sarcoendoplasmic reticulum Ca-ATPase 2 (SERCA2), encoded by ATP2A2, is a key protein involved in intracellular Ca homeostasis. The SERCA2a isoform is predominantly expressed in cardiomyocytes and type I myofibres. Variants in this gene are related to Darier disease, an autosomal dominant dermatologic disorder, but have never been linked to myopathy.

Papular acantholytic dyskeratosis (PAD) of the vulva is an uncommon benign condition characterized by multiple hyperkeratotic papules in the anogenital region. First described in 1984, PAD belongs to the spectrum of focal acantholytic dyskeratoses and shares histopathological features with Darier disease and Hailey-Hailey disease. Despite its persistence, PAD is benign, requiring only reassurance in many cases.
