MeSH continued the work begun in 2010 of merging the list of rare disease terms maintained by the Office of Rare Diseases Research (ORDR) into the MeSH vocabulary. The rare disease terms that matched existing MeSH descriptors were merged with those MeSH descriptors. The remainder were introduced as Supplementary Concept Records (Class 3) in MeSH 2011. As with all SCRs, each of these rare disease SCR terms was mapped to ("Heading Mapped to") at least one current MeSH disease term to help searching and indexing. For example, Snyder Robinson Syndrome is a new disease SCR that is mapped to the MeSH descriptor Mental Retardation, X-Linked. Both of these terms will appear in a MEDLINE citation if the SCR is assigned by the indexer. Because rare diseases are defined as having a prevalence of fewer than 200,000 affected individuals in the United States they traditionally received less attention and are sometimes called orphan diseases. Having these terms available for indexing purposes will enhance a more precise retrieval of the rare disease articles and contribute to their identification. DRAFT, 10/17/05
