Insomnia might be in your genes

IANS  |  New York 

Finding it difficult to Blame your genes, say researchers, who identified specific genetic factors that may trigger the development of problems.

The findings established that was linked to the occurrence of specific variants on chromosome 7.

It also demonstrated a genetic link between and and physical conditions.

"The genetic correlation between disorder and other psychiatric disorders, such as major depression, and such as type 2 suggests a shared genetic diathesis for these commonly co-occurring phenotypes," from the

"A better understanding of the molecular bases for insomnia will be critical for the development of new treatments," Stein added.

The variant on chromosome 7 is close to AUTS2 -- a gene that has been linked to alcohol consumption, as well as others that relate to brain development and sleep-related electric signalling, the researchers said.

"Several of these variants rest comfortably among locations and pathways already known to be related to and circadian rhythms," Stein said.

"associated loci may contribute to the genetic risk underlying a range of health conditions including and metabolic disease," he said.

Twin studies in the past showed that various sleep-related traits, including insomnia, are heritable.

Based on the findings, researchers started to look into the specific gene variants involved.

In the new study, appearing in the journal Molecular Psychiatry, the team analysed DNA samples from more than 33,000 soldiers, who were of European, African and Latino descent.

Stein also compared their results with those of two recent studies that used data from the

Overall, the study confirms that insomnia has a partially heritable basis.
