How tall you are is strongly related to the genes you inherit, and previous studies suggested that as much as 80% of the variance in height among people is due to their DNA.
And in the largest genetic study of height-related genes to date, scientists involved in the appropriately titled GIANT consortium (Genetic Investigation of Anthropometric Traits) identified 423 genetic regions connected to height — which could explain as much as 60% of that genetic component.
Dr. Joel Hirschhorn, leader of the GIANT consortium at Boston Children’s Hospital, Harvard Medical School and the Broad Institute of MIT says that for a trait like height, which isn’t determined by a single gene but likely the combined effects of multiple genes involved in multiple different processes from bone growth to cell growth, the new findings are like finding biggest nuggets of gold in a riverbed. The latest analysis, published in the journal
