Poor sleep linked to genetics: Study

IANS  |  London 

Suffering from disorder? Blame genetics. A new study has found several parts of our that could be responsible for poor

Researchers from the (MGH) and the identified as many as 47 links between our and the quality and quantity of

Among the genomic regions discovered is a gene called PDE11A. The team found that an uncommon variant of this gene affects not only how long one sleeps but also the quality of sleep.

"This study identifies genetic variants influencing sleep traits, and will provide new insights into the molecular role of sleep in humans," said from the

"Changes in sleep quality, quantity and timing are linked to such as and obesity, and psychiatric disorders," added from the varsity.

The study, published in the journal Nature Communications, the researchers looked at data from 85,670 participants of and 5,819 individuals from three other studies, who wore accelerometers-wrist-worn devices, which record activity levels continuously.

They found that collectively, the genetic regions linked to sleep quality are also linked to the production of serotonin-a neurotransmitter associated with feelings of happiness and wellbeing. Serotonin is known to play a key role in sleep cycles and is theorised to help promote deeper and more restful sleep.

They also found that is linked to poorer sleep from the genetic variants associated with sleep measures derived from the accelerometer data.
