Inborn Errors of Metabolism

In Germany, approx. 100,000 people suffer from a rare inborn error of metabolism; each of these diseases affects fewer than 2,000 persons. The term orphan diseases is distinctive; it is used to define diseases affecting a number of individuals who are often left behind when it comes to medical care. The purpose of the ASIM is to improve the medical treatment of these patients.

Various metabolic mechanisms can be affected, thus, widely differing diseases may occur.

    • Phenylketonuria (PKU), more details on Phenylketonuria
    • Maple sirup urine disease (MSUD)
    • Tyrosinaemia
