Heterotaxy, Visceral, 4, Autosomal; Htx4

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 the genetic heterogeneity of visceral heterotaxy, see HTX1 (OMIM ).
