Newborn screening follow-up and assessment with rapid laboratory assessment and collaborative management with primary care physicians. Lysosomal storage disorders diagnosis and management with enzyme replacement. Molecular genetic testing with assessment of family members at risk.


Diagnosis and multi-system clinical assessment. Molecular genetic testing. Coordinated ongoing care and anticipatory guidance with collaboration of multiple specialists in neurology, surgery, dermatology, renovascular disease, orthopedics, ophthalomology and oncology for both adults and children.

Collaborative Clinical Research

Under the direction of Michele Spencer-Manzon, MD, Yale is engaged in two important collaborative clinical research projects.

  • Urea Cycle Disorders Consortium - this consortium is engaged in research in the incidence, outcome, and treatment of inherited disorders of ammonia metabolism. For more information please Dr. Spencer-Manzon.
  • Phenylketonuria: Response to Phenoptin - this consortium is engaged research in the response of phenylketonuria to supplementation with tetrahydrobiopterin. Enrollment for the current trial is closed, but inquiries about the next protocol are welcome. For more information, contact Nurse Coordinator, Brittany Holmes, APRN.
