.... Among the human-only duplications, some of those sections of the genome are implicated in human developmental disorders such as spinal muscular atrophy and Prader-Willi syndrome. Parts of those duplicated segments have only single copies in the chimp genome, and it is possible that the chimpanzee is therefo...Collaborative Cross to provide powerful resource for mouse model researchers worldwide

...esearchers worldwide are seeking to define ancient sections of our genetic code that may soon be as important to medical science as genes. A new wave of research is concerned with, not how genes work, but how small regulatory DNA sequences tell genes where, when and to what degree to "turn on."
