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. NCL is almost always inherited as an autosomal recessive trait. 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. Some progress has been made toward the above-stated goal. A mutation in CLN8 is responsible for NCL in English Setters (Katz et al 2005) |
L'ataxie cérébelleuse héréditaire est une maladie neurodégénérative entraînant une perte de motricité et de vision, ainsi que des troubles comportementaux. Une mutation concerne le gène RAB24 : La seconde mutation concerne le gène CNL8 : Le laboratoire ANTAGENE a mené une étude afin dévaluer la fréquence de porteurs en France chez le Setter Gordon. La fréquence allélique est de 24%. Etiologie : Conduite à tenir : |
