About 99% of mouse genes have a homolog in the human genome, and for 80% of these genes, the best match in the human genome has, in turn, its best match against the orthologous mouse gene in the conserved syntenic interval.
Animals are biologically similar to humans. In fact, chimpanzees share more that 99% of DNA with humans and mice share more than 98% DNA with humans, therefore, animals are susceptible to many of the same health problems as humans.
