E-mail: fpalau@ibv.csic.es <h3>SPECIFIC AIMS</h3> Work on model systems has proven to be essential to understanding frataxin function and therefore the pathogenic basis of Friedreich ataxia (FRDA). The aim of this work was to determine the results of reproducing the diminution of frataxin function observed in FRDA patients in the nematode Caenorhabditis elegans . This is the first step in establishing a new animal model for the study of frataxin function, which also has great potential for testing drugs to treat Friedreich ataxia. <h3>PRINCIPAL FINDINGS</h3> 1. Identification and characterization of frh-1<h3>, the C. elegans FRDA ortholog</h3> We identified the C. elegans homologue of the human
