Genomes and Genes
Affiliation: Foundation IRCCS Institute of Neurology "Besta"
Location: Milan, Italy
The main interest of Dr. Ghezzi is the discovery of new genes responsible for mitochondrial disorders and the characterization of their role. These disorders are very heterogeneous and hence the diagnosis is often difficult. Moreover mitochondrial dysfunctions are now clearly related to a wide range of disease conditions, above all neurodegeneration (i.e. Parkinsons disease).
