Is height determined by genetics?

Scientists estimate that about 80 percent of an individual’s height is determined by the DNA sequence variants they have inherited, but which genes these variants are in and what they do to affect height are only partially understood. Some rare gene mutations have dramatic effects on height (for example, variants in the FGFR3 gene cause achondroplasia, a rare condition characterized by short stature). For most individuals, though, height is controlled largely by a combination of genetic variants that each have more modest effects on height, plus a smaller contribution from environmental factors (such as nutrition). More than 700 such gene variants have been discovered and many more are expected to be identified. Some of these variants are in genes that directly or indirectly affect cartilage in growth plates, which are areas in the long bones of the legs and arms where new bone is produced, lengthening the bones as children grow. The function of many other height-associated genes remains unknown

“We are starting to get a general sense of the landscape; we’ve definitely pointed to a number of specific genes that are quite important in height,” says Hirschhorn, who estimates that a third of the genetic contribution to height is now accounted for. “But there are still many genes that we don’t understand what they do. We need a combination of more genetics and biology to put it all together.” Said a Scientist

Scientists find a gene that makes some people taller

The first gene linked to tallness, one of the most heritable of traits, has been discovered by scientists, a finding that is expected to shed light on human development and further understanding of cancer. An international team including researchers at Oxford and Exeter analysed DNA from 35,000 people and found that a single letter in the human genetic code was responsible for making some people taller than others.

The scientists zeroed in on a gene called HMGA2, of which we inherit two copies, one from each parent. Inheriting a form of the gene that has a C written into the genetic code instead of a T adds about half a centimetre to a person's height, the scientists found, while inheriting two copies adds nearly a full centimetre.

The discovery is the first to identify a single gene that directly influences natural variation of height. Around a quarter of white Europeans will carry two versions of the "tall" version of the gene, with another quarter carrying two "short" versions
