NCT02311283

Brief Summary

The purpose of this study is to determine if patients participating in "The Longitudinal Study of Urea Cycle Disorders" are different than participants in the Urea Cycles Disorders Consortium (UCDC) Rare Diseases Clinical Research Network (RDCRN) Contact Registry and to determine if patients are a good source of medical information.

Outcome Measures

Primary Outcomes (3)

  • Test the feasibility of collecting survey data from the UCDC Contact Registry

    Patient-reported survey data will be reviewed for accuracy and feasibility as a reliable data source.

    Up to one year from study activation.

  • Assess patient reported outcomes on urea cycle relevant dimensions (applied cognition & subjective well-being).

    The PROMIS website will be used to assess the accuracy and completeness of patient reported outcomes on urea cycle relevant dimensions.

    Up to one year from study activation.

  • Validate data on treatment setting (team and organization) and management (diet, pharmacologic management, transplantation)

    Patient-reported survey data will be linked with research data collected in clinic for the same patients to validate patient-reported data on treatment setting and disease management.

    Up to one year from study activation.

Study Population

Patients with urea cycle disorders will be recruited via the RDCRN UCDC Contact Registry. The UCDC contact registry consists of over 300 participants with urea cycle disorders.

You may qualify if:

  • Enrollment in UCDC RDCRN Contact Registry
  • Patient reported diagnosis of one of the eight UCDs or UCD diagnosis highly likely/pending.

You may not qualify if:

  • Cases of hyperammonemia caused by an organic acidemia, lysinuric protein intolerance, mitochondrial disorders, congenital lactic acidemia, fatty acid oxidation defects and primary liver disease.
  • Individuals with rare and unrelated serious comorbidities, e.g., Down syndrome, intraventricular hemorrhage in the newborn period, and extreme low birth weight (\<1,500 grams).
  • Inability to provide informed consent and complete surveys
