CAMPISTOL, Jaume. Inborn errors of metabolism. Advances in diagnosis and therapeutic. Medicina (B. Aires) [online]. 2023, vol.83, suppl.4, pp.3-8. ISSN 0025-7680.

The advances in the field of inborn errors of metabo lism (IEM) are spectacular. New IEM have been described, their pathophysiological bases and implications for the organism are better known. With the advent of new metabolomics, lipidomics and genomics techniques, advances in diagnosis have multiplied and allow new therapeutic options to be explored. A new IEM classi fication has been established based on the more than 1.450 IEM identified. A new specialty is emerging, which is metabolic medicine. Neonatal screening is becom ing universal and allows us today, with tandem mass, to diagnose more than 20 metabolic diseases of the neonatal period, with treatment options. IEM units for adults are being created to follow-up children with IEM who survive the disease and with an increasingly better quality of life, and some IEM that start in adolescence or adulthood are diagnosed. Personalized therapies and clinical practice guidelines appear for any IEM. Finally, new therapeutic options are emerging day to day that allow a longer survival and better quality of life. Con ventional gene therapy is already being applied in some IEM. However, gene editing strategies with RNA thera pies may allow the correction of the genetic mutation, minimizing the problems associated with conventional compensation gene therapy.
