Description : Heterotaxy ('heter' meaning 'other' and 'taxy' meaning 'arrangement'), or situs ambiguus,
is a developmental condition characterized by randomization of the placement of visceral
organs, including the heart, lungs, liver, spleen, and stomach. The organs are oriented
randomly with respect to the left-right axis and with respect to one another (Srivastava,
1997). Heterotaxy is a clinically and genetically heterogeneous disorder. For a discussion
of genetic heterogeneity of visceral heterotaxy, see HTX1 (306955).;
