Depression: a genetic legacy of Neanderthals
We already knew, thanks to a study published in January in the American Journal of Human Genetics, the genes inherited from Neanderthals were responsible for excessive sensitivity of the immune system that can cause allergies (asthma, hay fever .. .).
Genes NĂ©andertal causing depression
According to a new study published February 11, 2016 in the journal Science, that genetic transmission would also be the cause of depression.
We would have inherited 4% of genes of Neanderthals disappeared there are about 30 000 years. The Neanderthal and the future modern man (Homo sapiens) have indeed lived in Europe for the same period between 40,000 and 33,000 years.
The latest US study compared the Neanderthal DNA in the genomes of 28,000 adults of European descent with their medical records. The DNA of volunteers contained over 135,000 genetic variations from Neanderthals.
increased risk of depression, stroke and blood diseases
The researchers then determined the relationship between these variants and disease. "The DNA of Neanderthals influences the clinical features of people today, says John Capra assistant professor of biology at Vanderbilt University (Tennessee), lead author of the research.
We have discovered a relationship between the DNA of Neanderthals and a wide range of immunological, dermatological, neurological, psychiatric traits and with the reproductive system diseases, "he says.
Also, they discovered that some of the Neanderthal genetic variations were linked to an increased risk of certain diseases including depression, myocardial myocardeet of blood disorders.
