How might hyperprolinemia type 2 be treated?

There is no specific treatment for hyperprolinemia type 2, even for those individuals who experience seizures. In general, if people with hyperprolinemia type 2 have symptoms, they are usually mild and do not require treatment. If seizures are present during childhood, they tend to disappear in adulthood. Attempts to reduce the amount of proline in an affected person's diet have resulted in only modest control of proline levels in the blood and have not reduced symptoms.[1]
