Mission Accomplished? What novel gene discovery teaches us about leukodystrophies
Leukodystrophies remain a diagnostic challenge for practitioners and families. Next generation sequencing (NGS) offers exciting opportunities to expand our understanding of disease phenotypes and to explore pathophysiologic mechanisms, based on the molecular cause of abnormalities in central nervous system white matter. The diagnostic odyssey and its implications are discussed, from the perspective of an Australian family. Additionally, an update is provided on the contributions of NGS to the description of novel leukodystrophies and their treatments in this ever expanding field.
