Heterotaxy, or situs ambiguus, is an abnormal arrangement of the thoracic and abdominal viscera. The phenotype with mirror-image reversed left-right axis is called situs inversus, while partial alterations in the left-right organization is referred to as heterotaxy. Heterotaxy is associated with perturbation of nodal signaling during embryogenesis.
