Brain architecture linked to genetic regions in left-handed people

For the first time, researchers have identified that left-handed people in the general population may have specific genes that are associated with left-handedness and have linked their effects to brain architecture. Through twin studies it has already been identified that genes play a partial role in determining handedness, but which genes these are had not been established in the general population. In this recent study, which has been published in the journal Brain, researchers identified some of the genetic variants associated with left-handed people by analyzing the genomes of approximately 400,000 people from the UK Biobank, which included 38,332 left-handers....
