Weill-Marchesani syndrome (WMS) is a rare disease characterized by short stature, brachydactyly, joint stiffness, and characteristic eye abnormalities, including microspherophakia, ectopia lentil, and glaucoma. Both autosomal recessive and autosomal dominant modes of inheritance have been described in association with WMS. We have performed a genome-wide search in two large consanguineous families of Lebanese and Saudian origin consistent with an autosomal recessive mode of inheritance. Here, we report the linkage of the disease gene to chromosome 19p13.3-p13.2 (Zmax=5.99 at 0=0 at locus D 195906). A recombination event between loci D 195905 and D 195901 defines the distal boundary. and a second recombination event between loci D 19S221 and D 19S840 defines the proximal boundary of the genetic interval encompassing the WMS gene (12.4 cM). We hope that our ongoing studies will lead to the identification of the disease-causing gene.
