Canine Ceroid Lipofuscinoses (CCL)/

Neuronal Ceroid Lipofuscinoses (NCL)

The neuronal ceroid-lipofuscinoses (NCLs) are a class of inherited neurological disorders that have been diagnosed in dogs, humans, cats, sheep, goats, cynomolgus monkeys, cattle, horses, and lovebirds. Among dogs, NCL has been reported in many breeds, including English Setters, Tibetan Terriers, American Bulldogs, Dachshunds, Polish Lowland Sheepdogs, Border Collies, Dalmatians, Miniature Schnauzers, Australian Shepherds, Australian Cattle Dogs, Golden Retrievers, and other breeds. NCL is almost always inherited as an autosomal recessive trait. In humans, mutations in one of at least six different genes can lead to NCL. Mutations in several other genes have been found to be responsible for NCL in one or more animal species.

 

All of the NCLs have two things in common: pathological degenerative changes occur in the central nervous system, and nerve cells accumulate material that is fluorescent when examined under blue or ultraviolet light. Although neurological signs are always present in canine NCL, these signs vary substantially between breeds and can overlap with signs present in other neurological disorders. Until the gene defect responsible for NCL has been identified for a particular breed, a definitive diagnosis can only be made upon microscopic examination of nervous tissues at necropsy.
