Genetic studies of Unverricht-Luendborg disease
- McGill Univ., Montreal (Canada); and others
Unverricht-Luendborg disease (ULD) is a progressive myoclonus epilepsy with an age of onset between 6 and 13 years, myoclonic jerks that progressively worsen, and mental deterioration. ULD shows an autosomal recessive mode of inheritance. The ULD gene has been genetically linked to 21q22.3, and more recently estimated to lie within 0.3 cM of the markers PFKL, D21S25, and D21S154, based on linkage disequilibrium. We have previously identified eight families affected with ULD and shown linkage to 21q22.3. In our efforts to identify the metabolic basis of the disease, we have identified several other families with ULD and are testing them for linkage to 21q22.3 We are also constructing a cosmid and YAC contig of the candidate EPM1 region in 21q22.3 and are in the process of identifying candidate genes therefrom.
