Linkage analysis in juvenile neuronal ceroid lipofuscinosis.

Published

Journal Article

Neuronal ceroid lipofuscinosis (NCL, Batten disease) is an autosomal recessive disease characterized by progressive mental retardation, cortical atrophy, seizures, and retinal degeneration. Several subtypes have been delineated on the basis of age-at-onset and histological characteristics; the most common is the juvenile (JNCL) form. Recently, the gene for JNCL was shown to reside on chromosome 16 through linkage studies to the haptoglobin locus and anonymous DNA markers using numerous European families. We have now examined 8 families from North America with JNCL for linkage to markers in 16q21-23. Results in 3 families tend to support linkage to chromosome 16;3 families remained uninformative, and 2 families produced negative lod scores in this region. A test of homogeneity was suggestive, but could not significantly reject the null hypothesis of homogeneity. We are continuing to collect families, particularly those with multiple living affecteds, and are identifying other probes in this region. Given close localization on chromosome 16 for JNCL, molecular strategies, including candidate gene strategies, are being explored.
