Hereditary metabolic diseases are all rare diseases with an incidence < 1:10.000. They generally affect a number of different organ systems and present with significant clinical and biochemical heterogeneity. Metabolic profiling using (non-) targeted metabolomics together with molecular phenotyping identifying genetic determinants and modifiers unravel the complex metabolic pathway interactions resulting in disease.
