Do You Have A Qualifying Infant?

If you are not affiliated with a USIDNET enrolling center and have an infant who qualifies for the FILL program, we offer two enrollment pathways:
  1. Family Self-Consent: a parent of an infant who has been identified as having low lymphocytes can use a FILL-specific online consent form to enroll their child into the USIDNET Registry. Please refer the family to our participant portal.
  2. Become an Enrolling Center: only IRB-approved enrolling centers can enter data into the FILL registry. If you would like to set up your institution, please click here.
