Research confirms the gene region related to left-handed

About 10% of the population is left-handed British researchers report in the new British Journal brain that they have identified regions of the human genome related to left-handed people and found that some of them are related to brain structure Previous studies of twins have found that about 25% of left-handed children are inherited, but it is not clear which genes determine them The Oxford team analyzed the genome data of about 400000 people in the British biological bank, including about 38000 left-handed people Through analysis, the researchers identified four regions of the human genome that are related to left handers, three of which are related to proteins that affect brain development and structure The proteins are involved in the formation of microtubules in brain cells, the researchers explained Microtubules are the main component of cytoskeleton, which is a kind of protein fiber network structure in the cytoplasm It not only plays an important role in maintaining cell morphology and internal structure, but also participates in a variety of life activities After brain imaging of about 10000 subjects, the researchers found that the genetic effects related to left-handed people were related to the structural differences of the brain white matter fiber bundle, which contains the cytoskeleton connecting the brain language area "We found that left-handed subjects' left and right brain language areas communicate with each other in a more coordinated way," said Weberg, one of the authors of the paper and a researcher at Oxford University, which provides an interesting direction for future research, that is, whether left-handed people have more advantages in performing "language tasks".
