Are you a 'night owl'? You may have this genetic mutation

This article is about how a single point mutation in the DNA sequence can have an effect on your sleeping patterns. More specifically, your circadian rhythm. The gene with the mutation is CRY1 and this affects the suppressors of the individuals circadian rhythm. This can extend their cycle by at least a half an hour, which can lead to a state of " perpetual jet lag". This isn't an impossible thing to get past though, just requires a stricter sleeping schedule.

My opinion is that this is interesting to learn about, mainly because I am one of these people. On the positive side, it is easier to get past the difficulties if there is enough motivation to get up, like getting something to eat.

Circadian Rhythm 


  1. This article is very interesting to me because I have always had difficulty going to sleep/waking up early. If I don't have a reason to, I often find it difficult to go to sleep before 1am and get out of bed before 11am. With an incentive, I can wake up early. However, nothing I have tried has resulted in me falling asleep before midnight since middle school. The idea that sleeping patterns can be affected by a mutation in the DNA sequence is a very interesting thought; one that might keep me up at night...

  2. That was a nice pun, Alex. But I also found this article very interesting. I also have the same problem trying to fall asleep, usually I go to bed by 3am. The fact that is could be due to a mutation is very interesting. We can also fix our mutation but going on a strict sleeping is very cool.
