Browse the GARD list of rare diseases and related terms to find topics of interest to you. This list includes the main name for each condition, as well as alternate names. Inclusion on this list does not serve as official recognition by the NIH that a disease is rare. Some conditions that are not considered rare are on this list and are labeled accordingly.Read more about which diseases are included on the GARD website.
