Mutations in the ADK gene cause an autosomal recessive Hypermethioninemia due to adenosine kinase deficiency.

This website provides information on patients with mutations in the ADK gene, including clinical data, molecular data, management and research options.

The syndrome caused by mutations in the ADK gene is a multisystem disorder characterized by global developmental delay, hypotonia, seizures, poor speech development, cerebral atrophy, white matter degeneration, intellectual disability, macrocephaly, hypertelorism, liver dysfunction, mild steatosis, and cholestasis.

Not all individuals with a mutation in the ADK gene have these features.

This website was created to share and collect information about clinic, management and research projects to gather more knowledge and provide better treatment of patients with mutations in the ADK gene.
