Gene regions associated with left-handedness are identified for the first time

Genes are known to play a part in determining hand-like sexStudies of twins estimate that 25 percent of the atherosclerosis can be attributed to genes, but these genes have not yet been identified in the general populationA new study published in the journal Brain shows that some genetic variants associated with left-handedness have been discovered by analysing the genomes of about 400,000 people at the UK's Biobank, including 38,332 left-handed peoplethree of the four gene regions they found were associated with proteins involved in brain development and structureOf particular note is the link between these proteins and microcells, which are part of intracellular stents (cytoskeletons)The role of cytoskeleton is to guide the construction and function of cells in the human bodydetailed brain imaging of about 10,000 participants, the researchers found that these genetic effects were associated with differences in white matter in the brain, which contains cytoskeletons in areas of the brain that connect language- to language"About 90 per cent of people are right-handed, and this has been going on for at least 10,000 years, " says DrAkira Weiberg, a researcher at the University of Oxford who lead the new study at theMany people have studied the biological basis of hand habits, but with the large data set at the BMA, we can get a clearer picture of the processes that lead to left-handednessstudy found that in left-handed subjects, the language regions of the left and right brain interacted in a more coordinated way, which may indicate that left-handed people may have an advantage in performing language tasksBut they also stress that these differences are considered average only, not all left-handed, left-handed people are at an extremely low risk of developing Parkinson's disease, but have a higher risk of schizophreniaBut the researchers also point out that this is a simple correlation, withno causation, and that studying these genetic associations could help us better understand how these serious diseases developresearchers concluded by saying that we have shown that left-handedness is the result of brain development, driven in part by the complex interaction sins of many genes, which also reflects the richness of humans.
