Genetic heterogeneity of neuronal ceroid lipofuscinosis in The Netherlands.
An overview of patients in the Netherlands who are known to us with neuronal ceroid lipofuscinosis (NCL) is presented. Several CLN genes involved in NCL have been isolated or mapped. We have analyzed families with different types of NCL with polymorphic markers linked to CLN loci to investigate the genetic heterogeneity of NCL in the Netherlands. Haplotype analysis suggests that in addition to the CLN2 and CLN6 genes another gene is involved in at least one family with late infantile NCL in the Netherlands. The CLN2 and CLN6 loci have also been excluded in a family with protracted juvenile NCL.
