The ULF is currently rewriting the content linked in the list below. We are working with our Medical and Scientific Advisory Board, our Board of Directors, and a handful of other leukodystrophy experts to get these pages updated as quickly as possible. Thank you for your patience, as we work on this section of our website! Our goal is to have a clickable link for each type, which will be updated periodically in the future as new information becomes available.
