USP7

What is USP7?

Welcome to the Foundation for USP7 Related Diseases! We are a registered 501(c)(3) non-profit organization dedicated to those who are affected by a mutation of the USP7 gene. A mutation of USP7 causes a neurodevelopmental disorder. Those affected are often developmentally delayed, have white matter abnormalities, speech impairment, are diagnosed with Autism Spectrum Disorder and more.

USP7 is a protein-coding gene that plays a role in tumor suppression, transcriptional regulation, immune response, and endosomal protein recycling. Individuals who are born with a mutation in USP7 have been found to have a neurodevelopmental disorder.


Mutations are either point mutations or gene deletions. Mutations are diagnosed through either whole-exome sequencing or chromosome microarray analysis. The inheritance pattern of the disease caused by USP7 mutations is autosomal dominant, which means that someone who receives a single copy of an abnormal USP7 gene from either parent may have this disorder.

Mutations are either point mutations or gene deletions. Mutations are diagnosed through either whole-exome sequencing or chromosome microarray analysis. The inheritance pattern of the disease caused by USP7 mutations is autosomal dominant, which means that someone who receives a single copy of an abnormal USP7 gene from either parent may have this disorder.

Once diagnosed, there are certain tests that are recommended for each patient. These tests include:

  1. Measurement of IGF-1 and IGF-BP3 to screen for growth hormone deficiency
  2. A brain MRI after 40 months of age to assess for abnormalities of white matter
  3. Full assessment by a speech pathologist
  4. Full assessment for physical and occupational therapy
  5. Formal cognitive and behavioral testing by a licensed pediatric psychiatrist 
  6. A sleep apnea test/sleep study
  7. An EEG test to test for abnormal electric activity that could cause/predispose seizures
  8. A consultation with a gastroenterologist for any reflux, vomiting, or chronic constipation/diarrhea issues
  9.  An assessment by a pediatric ophthalmologist

Those diagnosed with USP7 would benefit from early interventions, especially speech therapy, occupational therapy, and physical therapy.

Clinical Trials


Cords registry

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access.

Enrolling is easy.

  1. Complete the screening form.
  2. Review the informed consent.
  3. Answer the permission and data sharing questions.

After these steps, the enrollment process is complete. All other questions are voluntary. However, these questions are important to patients and their families to create awareness as well as to researchers to study rare diseases. This is why we ask our participants to update their information annually or anytime changes to their information occur.

Researchers can contact CoRDS to determine if the registry contains participants with the rare disease they are researching. If the researcher determines there is a sufficient number of participants or data on the rare disease of interest within the registry, the researcher can apply for access. Upon approval from the CoRDS Scientific Advisory Board, CoRDS staff will reach out to participants on behalf of the researcher. It is then up to the participant to determine if they would like to join the study.

Visit sanfordresearch.org/CoRDS to enroll.
