Dextrocardia is formed by the disruption of the normal left-right (L-R) asymmetry of the thoracoabdominal organs.Asymmetric expression of Nodal,Pitx2,Cited2 have affected L-R asymmetry of vertebrate significantly,and generated dextrocardia,mesocardia,ectopia cordis,heterotaxy and so on.Dextrocardia is often accompanied by congenital cardiac malformation.Therefore,it is so difficult to be treated that it has poor prognosis.This paper reveiws the molecular mechanism and it's regulation of dextrocardia for proceeding the genetic diagnosis and early intervention of dextrocardia sequentially in order to improve the survival rate and life quality of patients.
Key words:
