Methionine adenosyltransferase
Abstract Inherited methylation disorders are a group of rarely reported, probably largely underdiagnosed disorders affecting transmethylation processes in the metabolic pathway between methionine and homocysteine. These are methionine adenosyltransferase I/III, glycine N-methyltransferase, S adenosylhomocysteine hydrolase and adenosine kinase defi ciencies. This paper provides the first consensus recommenda tions for the diagnosis and management of methylation …
