  • Names
    • Undifferentiated connective tissue disease
    • Undifferentiated connective tissue syndrome
    Abbreviations: UCTD
    Category: Systemic
    Incidence From 46,662 to 466,620 cases in the US per year (Spinillo 2017). Female/Male ratio: No data.
    Age of Onset Onset typically occurs between ages 30 and 50.
    Description Patients of undifferentiated connective tissue disease (UCTD) share some, but not all, symptoms with other connective tissue diseases, such as systemic lupus erythmatosus, systemic sclerosis, dermatomyositis, polymyositis, rheumatoid arthritis, Sjogren's syndrome, and antiphospholipid syndrome. UCTD is diagnosed when a patient has a positive serum ANA test and shows stable symptoms for a minimum of 3 years. UCTD is distinct from the other above-mentioned diseases in that the condition remains stable over time without worsening. 30% of patients diagnosed with UCTD will be given a new diagnosis because their disease will not remain stable.

    Not confirmed as an autoimmune or autoinflammatory disease.

      Data Source: Graphs on this page represent data in electronic health records and self-reported survey results from the All of Us research database. As of July 2024, there are 451,000 sets of electronic health records and over 560,000 participants who have completed initial survey questions. This dataset, however, may not be representative of the US population. A snapshot of the data can be found here. To protect participant anonymity, results derived from fewer than 20 participants are not graphed.

      Data Source: Graphs on this page represent data in electronic health records from the All of Us research database. As of July 2024, there are 451,000 sets of electronic health records collected from participants. In the United States, because electronic health records use billing codes for diagnoses, some conditions may not be perfectly captured by these data, especially if the condition is rare. A snapshot of the data can be found here. To protect participant anonymity, results derived from fewer than 20 participants are not graphed.
