Question: Can sleep problems be linked with DNA?

Indeed it can! 🙂 We uses model that carry particular DNA changes, by changing one gene at a time, we can directly relates the DNA change to the model’s sleep/wake pattern. So far, we had example of extended sleep cycle, shortening sleep period and more recently, we are working on a genetic mutation model that wake up and sleep at completely random hour!
