Abstract PDF: Neurodegenerative disorders associated with high basal ganglia iron are known by the overarching term of ‘NBIA’ disorders or ‘neurodegeneration with brain iron accumulation’. Discovery of their individual genetic bases was greatly enabled by the collection of DNA and clinical data in just a few centers. With each discovery, the remaining idiopathic disorders could be further stratified by common clinical, radiographic or pathological features to enable the next hunt. This iterative process, along with strong and open collaborations, enabled the discoveries of PANK2, PLA2G6, C19orf12, FA2H, WDR45, and COASY gene mutations as underlying PKAN, PLAN, MPAN, FAHN, BPAN, and CoPAN, respectively. The era of Mendelian disease gene discovery is largely behind us, but the history of these discoveries for the NBIA disorders has not yet been told. A brief history is offered here.
