Linkage disequilibrium mapping of the gene for Margarita Island ectodermal dysplasia (ED4) to 11q23.
Margarita Island ectodermal dysplasia (ED4) is an autosomal recessive disorder characterized by unusual facies, dental anomalies, hypotrichosis, palmoplantar hyperkeratosis and onychodysplasia, syndactyly, and cleft lip/cleft palate. We have used an affected-only DNA-pooling strategy to carry out linkage disequilibrium mapping of the ED4 gene to 11q23. Haplotype analysis of four complex Margarita Island ED4 families localized the ED4 gene to an approximately 1-2-Mb interval spanned by just two YACs.
