Is Whipple disease genetic?
Is Whipple’s Disease Hereditary? Unlike some diseases with clear hereditary causes, T. whipplei infections are caused by bacteria, so theoretically anyone who comes into contact with Tropheryma Whipplei bacteria could be at risk for infection.
Is there a test for Whipple disease?
