Comprehensive Study Discovers Gene Regions Linked With Sleep Duration

A study conducted by scientists from MGH (Massachusetts General Hospital) and the UEMS (University of Exeter Medical School) has found 76 new gene regions linked with sleep duration. The research by a team that in recent time reported finding gene locations linked with insomnia menace and chronotype, which is the inclination to be an untimely riser or to be a “night owl.” The study was published in Nature Communications. Hassan Saeed Dashti—of the MGH’s CGM (Center for Genomic Medicine)—stated, “While we use up almost a third of our life in sleeping, we have less awareness of the particular pathways and genes that control the amount of sleep people get. Our research suggests that several of the genes significant for sleep in animal prototypes might also affect sleep in humans and sheds the light on the better understanding of the regulation and function of sleep.”

It is well known that frequently getting sufficient sleep (7–8 Hours every night) is imperative to health, and both inadequate sleep (6 or fewer hours) and extreme sleep (9 Hours or more than that) have been associated to significant health issues. Family studies have suggested that from 10% to 40% of disparity in sleep duration might be inherited, and earlier genetic studies have linked alternatives in two gene areas with sleep duration. The present study, which is the largest of its type to address sleep duration, examined genetic data from over 446,000 participants in the U.K. The GWAS (genome-wide association study) found 78 gene regions—counting the two earlier identified—as linked with sleep duration.

On a similar note, recently, a study showed an association amid sleep duration and the growth of diabetes. This can reflect the causal impacts of sleep on diabetes, or sleep duration might be the outcome of other parameters that lead to diabetes. No uncertain controlled trials have reviewed the impact of sleep on diabetes, and such research would be difficult to carry out.
