Rapid diagnostic test for the major mutation underlying Batten disease.
Abstract
Batten disease is the most common progressive neurodegenerative disorder of childhood in western countries. A novel cDNA responsible for Batten disease has recently been identified. We have developed a rapid diagnostic solid phase minisequencing test to detect the major 1.02 kb deletion which is responsible for 81% of affected chromosomes in Batten disease worldwide. In Finland, 90% of Batten chromosomes carry the major deletion owing to the enrichment of the CLN3 gene in the isolated Finnish population.
