A study published in the journal of Nature Genetics reports that the DNA most often influences a person’s height. This confirms hereditary as the most important influence on a person’s height.
Scientists examined DNA from 35,000 people and found that a gene known as HMGA2 had a different coding to indicate a person’s height. A C code instead of a T code was found in people who are taller.
Dr. Joel Hirschhorn, Associate Professor of Genetics at Harvard Medical School says,

Because height is a complex trait, involving a variety of genetic and non-genetic factors, it can teach us valuable lessons about the genetic framework of other complex traits such as diabetes, cancer and other common human diseases.

Linking height to DNA is just the first step in using DNA to identify many different human variables, the researchers report. “Soon the scientific community will have access to many more large-scale genomic data sets, making it feasible to identify additional genes involved in height,” Hirschhorn added.
