Inherited Metabolic Disease Program

The ColumbiaDoctors Inherited Metabolic Disease Program is a comprehensive program designed to diagnose, manage and counsel patients with inherited metabolic disorders and their families.

Inherited metabolic disorders, also known as Inborn Errors of Metabolism (IEM), are a group of individually very rare disorders, but as a group common, that can affect patients of any age from the newborn period well into adulthood. Moreover, since the introduction of expanded newborn screening for IEM in the last 10 years, the number of patients diagnosed with these conditions has increased dramatically. Thus, the need for a dedicate team of health providers and ancillary personnel is critical.

Our multidisciplinary program offers all the necessary components for successfully care for these patients. The team includes a board certified biochemical geneticist, a biochemical geneticist, a specialized nurse practitioner, a metabolic dietitian and a social worker. We offer an in-house biochemical laboratory to perform very specialized tests that are necessary for the diagnosis and management of these patients.

In addition, a steady supply of special formulas (medical foods) and specialized medications are available. We provide service 24 hours a day, all year long. Therefore, patients and parents are assured that care will be provided uninterrupted even is if after hours, on a holiday or over the weekends. Due to the possibility of acute decompensations, it is critical to have coverage 24/7/365, and therefore, being able to provide it makes all the difference for the patients and their families.
