It was clearly established that juvenile neuronal ceroid lipofuscinosis (JNCL) or Batten disease (CLN3; OMIM #204200) is caused by homozygous or compound heterozygous mutation in the CLN3 gene (NCBI ID 1201, HGNC ID 2074, MIM ID 607042) located on the short arm of the Homo sapiens chromosome 16 at position 12.1 (16p12) [5]. This evidence concerns the gene CLN3 and infantile neuronal ceroid lipofuscinosis.
