A novel mutation in the ARS (component B) gene encoding SLURP-1 in a family with Mal de Meleda.

Mal de Meleda is a rare, autosomal recessive form of palmoplantar keratoderma. The disease has been mapped to chromosome 8 qter, and recently mutations in the ARS (component B) gene have been identified in families with this disorder. We describe a small family of Turkish origin with Mal de Meleda and identified a novel homozygous mutation, L98P, in ARS (component B). These findings extend the body of evidence implicating mutations in the ARS (component B) gene in Mal de Meleda.
