We have developed a comprehensive database (MITOMAP) for the human mit
ochondrial DNA (mtDNA), the first component of the human genome to be
completely sequenced [Anderson et al. (1981) Nature 290, 457-465]. MIT
OMAP uses the mtDNA sequence as the unifying element for bringing toge
ther information on mitochondrial genome structure and function, patho
genic mutations and their clinical characteristics, population associa
ted variation, and gene-gene interactions. As increasingly larger regi
ons of the human genome are sequenced and characterized, the need for
integrating such information will grow. Consequently, MITOMAP not only
provides a valuable reference for the mitochondrial biologist, it may
also provide a model for the development of information storage and r
etrieval systems for other components of the human genome.
