Neuronal Ceroid Lipofuscinosis 5 (NCL5) – Golden Retriever
Neuronal Ceroid Lipofuscinosis (NCL) is the name referring to a wide array of degenerative neurological conditions which cause progressive nerve damage, resulting in a loss of mobility and vision, and ultimately death. This variant, occurring in the Golden Retriever, is the result of a recessive mutation to the CLN5 gene. A similar mutation also occurs in the Australian Cattle Dog and Border Collie.
