Type of disease: Rare conditions
Situs inversus is a condition in which the internal organs of the abdomen (stomach) and thorax (chest) lie in mirror image of their normal body position. It can occur alone, without any other anomalies, or it can be a part of a syndrome with various other defects. Situs inversus has been inherited in different ways in different families. Autosomal dominant, autosomal recessive, and X-linked inheritance have been reported. Treatment, when needed, is symptomatic and supportive.
