Autosomal recessive anhidrotic ectodermal dysplasia in a large Moroccan family.

We studied a large Moroccan family in which anhidrotic ectodermal dysplasia is transmitted as an autosomal recessive trait. Fourteen family members, both males and females, were affected and they all had a common ancestor. Linkage analysis by homozygosity mapping in this family will permit the gene localisation of this rare form of anhidrotic ectodermal dysplasia.
