Fragile X Syndrome in Adulthood: A Study of Electronic Health Records.

We analyzed the electronic health records of 323 Black and White non-Hispanic adults with Fragile X syndrome who were served by CAPriCORN, a network of healthcare systems in an urban area in the Midwest. Black patients with Fragile X syndrome were found to have a substantially elevated frequency of mental, neurological, and physical health conditions compared to Black controls. Further, Black and White patients with Fragile X syndrome had a dominant pattern of similarity across the hundreds of conditions that appeared in their records. This study broadens understanding of the health conditions associated with Fragile X syndrome during adulthood by extending the patient population to include Blacks as well as Whites.
