JNCL is a neurodegenerative disease of childhood caused by mutations in the
CLN3 gene. A mouse model for JNCL was created by disrupting exons 1-6 of C
ln3, resulting in a null allele, Cln3 null mice appear clinically normal at
5 months of age; however, like JNCL patients, they exhibit intracellular a
ccumulation of autofluorescent material, A second approach will generate mi
ce in which exons 7 and 8 of Cln3 are deleted, mimicking the common mutatio
n in JNCL patients, (C) 1999 Academic Press.
