title: Genetic linkage of Meleda disease to chromosome 8qter.
abstract: Meleda disease (mal de Meleda) MIM *248300 is an autosomal recessive disorder, clinically characterised by transgressive palmoplantar keratoderma, hyperhidrosis and perioral erythema. It was first described on the Adriatic island of Meleda, where it was relatively common. The prevalence in the general population is estimated to be 1 in 100,000. Linkage analysis of two large consanguineous families from Algeria, including 10 affected individuals, showed strong evidence for localisation of Meleda disease to chromosome 8qter with a maximum two-point lod score for D8S1751 of 8.21 at theta = 0. Analysis of homozygosity regions and recombination events places the gene in a region of at least 3 cM, telomeric to D8S1727. A common haplotype was observed in the two families, suggesting a founder effect.
