Welcome to the MitoBreak database project

A comprehensive on-line resource with curated datasets of mitochondrial DNA (mtDNA) rearrangements. MitoBreak provides a complete, quality checked and regularly updated list of breakpoints from: circular deleted mtDNAs (deletions) circular partially-duplicated mtDNAs (duplications) linear mtDNAs For more background information click here or read Damas J, et al. Nucleic Acids Research. 2014. 42 (D1): D1261-D1268.
