Batten disease, also known as Juvenile neuronal ceroid lipofuscinoses (JNCL), is an autosomal recessive lysosomal disease. It manifests with vision loss, followed by seizures and progressive neurodegeneration, robbing children of motor skills, speech and cognition, and eventually leading to death in the second or third decade of life. Loss-of-function mutations in CLN3 are responsible for Batten disease.
