    Gene expression in pediatric heart disease with emphasis on conotruncal defects.
    Prog Pediatr Cardiol 2005 Jul 9;20(2):127-141. Epub 2005 Jun 9.
    Section of Medical Genetics and Molecular Medicine, Children's Mercy Hospitals and Clinics and University of Missouri-Kansas City School of Medicine, 2401 Gillham Rd., Kansas City, MO 64108, United States.
    Developmental abnormalities of the heart are the underlying cause of many congenital heart malformations. The embryological development of the integrated cardiovascular tissue is the result of multiple tissue and cell-to-cell interactions involving temporal and spatial events under genetic control. Recent technological advances, like microarray analysis of gene expression, are providing new tools to aid in deciphering the complex networks of gene expression that regulate cardiac development.
