Does bowed legs (genu varum) run in families?

Bowlegs, medically known as genu varum or tibial vara, do not have a clear genetic inheritance pattern and are more commonly caused by postnatal factors. 1. Non-genetic perspective: Most studies and physicians believe that bowlegs are primarily caused by imbalances in the ligaments of the lower limbs or abnormalities in bone structure, rather than genetic factors. For example, joint ligament imbalance can often be corrected through targeted ligament strengthening exercises. Skeletal abnormalities are usually attributed to factors such as childhood calcium deficiency or vitamin D deficiency, and thus are not closely related to genetics. 2. Genetic predisposition: Some viewpoints suggest that bowlegs may exhibit a genetic predisposition. However, this inheritance is not direct, but rather potentially associated with familial lifestyle habits or indirect genetic influences. For families concerned about hereditary factors, it is recommended to pay attention to children's nutrition and lifestyle habits, and avoid factors that may contribute to the development of bowlegs.
