This means that altering a single base-pair in the gene’s lengthy DNA chain is enough to change someone’s sleep behavior. The lead author of the paper in Nature is Ying Xu, an associate of the group in San Francisco. Other team users are at the University of Vermont and the University of Utah.. A circadian rhythm gene discovered A few rare individuals who consistently nod off early, much before dawn then wake up wide-eyed, can blame a newly-found mutant gene because of their sleep troubles, Today Howard Hughes Medical Institute researchers announced.
