XLMR database

The computer database on X-linked mental retardation (XLMR) disorders developed by Arena and Lubs in 1991 has now been updated to include all currently known XLMR disorders and nonspecific (MRX) families. Currently, it includes 123 syndromes, 59 nonspecific XLMR families, and 60 families from the Miami/Greenwood study. The older clinical reports have been reviewed and revised. The search mechanism has also been revised and now includes 740 individual "keywords." Each of these keywords recognizes several of clinical descriptive terms, as used in published literature reports. Searches can be made according to any clinical finding or combination of findings. For each disorder, the database presents a graphic display that contains a revised and more complete set of clinical findings, references, keywords, map localization, molecular information, access to pictures, and OMIM number.
