The gene for Batten disease (CLN3) has been mapped to human chromosome 16 by demonstration of linkage to the haptoglobin locus, and its localization has been further refined using a panel of DNA markers.
In a material of 26 Caucasian families, 23 with at least 2 children affected with Batten disease, we found a lod score of 3.00 at theta = 0.00 in males and theta = 0.26 in females with haptoglobin (HP), and assign the locus for Batten disease to 16q22.
