Neuronal ceroid lipofuscinoses (NCLs) are a group of lysosomal storage diseases that affect the central nervous system, leading to early neuronal death and progressive neurodegeneration. NCL2 specifically affects dachshunds, with symptoms including vision loss, tremors, and coordination problems starting at a young age. Unfortunately, there is no known cure for NCL2, and affected dogs typically do not survive past 12 months of age.
