Bryony Thompson (Royal Melbourne Hospital)

Green List (high evidence)

Only 5 cases in 4 families reported thus far, and a supporting null mouse model. The clinical presentation of the reported cases (mild hepatomegaly and chronic elevation of the transaminase levels in the blood without liver disease) suggests a benign disorder, however hypermethioninemia is a reported risk factor for various neurological complications regardless of the cause.
