Greater height and long legs have been associated with greater risk of incident venous thromboembolism, but the results are still controversial. One of the reasons is height being also associated with the genetic and environmental factors. Hence, the co-sibling study was conducted to determine the relationship between the incidence of thromboembolism and height. This article reports the interesting outcomes of this study. It is a well known fact that height is highly heritable.

However, lesser known fact is the common genetic variants related to height are weakly associated with height. Moreover, studies indicate that 20% of the variation in the body height is because of the environmental factors. In poor societies influence of environmental factors might be stronger. Non genetic factors associated with body height include nutrition, diseases, socioeconomic status, and environmental…
