The Genetics of Sleep Duration

A late-breaking abstract (LBA 2) that will be presented later this morning as an oral presentation identified new genes associated with variations in sleep duration. The genome-wide association study involved 2,200 people in Finland; they were characterized for sleep length per night and evaluated for depressive symptoms and variation in mood.

The researchers found several new genes and variants that showed statistically significant association with total sleep length. Analysis also showed that sleep length and seasonal changes in mood share common molecular genes and pathways. This suggests that sleep disturbances and mood disorders may share common genetic components.

You can read the abstract in the
final program.


  1. I read your full blog and I enjoyed it.
    Can you please tell me some detail about this genes so that I am doing some research work on that?


  2. nice post i found here what i am searching for . Really this is a great blog thanks for sharing man

  3. Nice information,valuable and excellent design,as you shared good stuff with different ideas and concepts,lots of great information and inspiration, both of which I need, thanks for all the enthusiasm you offered with this helpful information here

  4. Well I don't know to much about this but rarely i sleep well and just a few hours and always wake up very tired like if i were all night in party.
