Decode the genetic secret of human height

There is nothing mysterious if your parents are tall, you will almost certainly be tall. However, it is always a great challenge for scientists to fully explain the principle of genetic genetics.

>>>Found genes related to height development in humans
>>> Discover 180 gene variants that regulate height

On October 5, experts from Children's Hospital Boston and the Institute of Cooperation between the Massachusetts Institute of Technology and Harvard University of the United States and a number of other countries announced the most sophisticated research ever in This field, which includes genetic data analysis of more than 250,000 Europeans, North American and Australians, and European ancestors, identifies nearly 700 gene variants and more than 400 gene domains related to height. human.

According to a study published in Nature Genetics, many genes have been identified to play an important role in regulating the development of human skeleton, but never before. known to be related to height issues.

It is estimated that human height is 80% due to the genotype specified, the rest is affected by diet and environmental factors.

The average height of people is higher and higher over several generations due to many reasons, including improved nutrition.

Professor Joel Hirschhorn, a researcher on infant genetics and endocrinology at Children's Hospital Boston, said over the past 100 years, genetic research has been linked to studies of obesity, diabetes, Asthma - the same diseases are caused by the overall effect of many types of genes interacting with each other.

Thus, by explaining how the genetic principle works in height, scientists hope to understand how the genetic principle of human diseases works.

According to Mr. Hirschhorn, by doubling the size of the study, experts have identified twice the number of gene regions involved in height, and up to seven times the number of actual genes they can create. linked to the development of ordinary human skeletons.

In previous research in 2010 on a small group of people, scientists identified 199 gene variants in 180 gene fields.

Meanwhile, genetic researcher Timothy Frayling of the University of Exeter in the UK says they have discovered gene variants - different DNA fragments in each person - accounting for 20% of the gene's composition compared to other variables. Normal form of height.

In addition, small stature in children is a major pathological problem for endocrinologist scientists in children. Explaining the genes and their variants that play an important role in height can help doctors diagnose children with the only underlying cause of their modest height , Professor Hirschhorn said. know more.

According to scientists, they will continue to study this issue in the future.
