    Biotin-Responsive Disorders

    Two inherited defects affecting the coenzyme function of biotin are known: holocarboxylase synthetase (HCS) deficiency and biotinidase deficiency. Both lead to deficiency of all biotin-dependent carboxylases, ...

    Disorders of Ornithine and Proline Metabolism

    Hyperornithinaemia due to ornithine aminotransferase (OAT) deficiency results from loss of function mutations in OAT and causes gyrate atrophy of the choroid and retina (GA), a progressive retinal degeneration. T...
