Choogon Lee, an associate professor in the Florida State University College of Medicine, has embarked on a four-year project to uncover molecular secrets about human circadian sleep disorders, reports Florida State University News.

In this new study, he plans to use the new genome-editing technique CRISPR to generate novel genetic mutations in mice emulating diverse sleep disorders in humans. Specifically, he and his team are looking at the most common type of genetic variation in the human genome: single nucleotide polymorphisms (SNPs), the same genetic variation that allows 23andMe and similar companies to trace your ancestry through DNA.
