Characterization of the canine CLCN3 gene and evaluation as candidate for late-onset NCL.

ABSTRACT:

Background

The neuronal ceroid lipofuscinoses (NCL) are a heterogenous group of inherited progressive neurodegenerative diseases in different mammalian species. Tibetan Terrier and Polish Owczarek Nizinny (PON) dogs show rare late-onset NCL variants with autosomal recessive inheritance, which can not be explained by mutations of known human NCL genes. These dog breeds represent animal models for human late-onset NCL. In mice the chloride channel 3 gene (Clcn3) encoding an intracellular chloride channel was described to cause a phenotype similar to NCL.

Results

Two full-length cDNA splice variants of the canine CLCN3 gene are reported. The current canine whole genome sequence assembly was used for gene structure analyses and revealed 13 coding CLCN3 exons in 52 kb of genomic
