Identifying gene expression profiles in hypoplastic left heart syndrome and age-matched normal controls

ABSTRACT: Affymetrix GeneChip Exon-1.0ST was used to study the differential gene profiles in RV (right ventricle) samples from neonates with HLHS (hypoplastic left heart syndrome) versus RV and LV (left ventricle) samples obtained from age-matched controls. Although few significant changes were observed in the genetic profiles between control LV and control RV, many genes passed the false discovery rate in comparing HLHS-RV to RV and LV control groups, with greater differential profiles noted between HLHS-RV and control RV. Myocardial samples were isolated from the RV of 6 HLHS neonates, diagnosed based upon clinical features including hypoplasia/atresia of the ascending aorta, various degrees of underdevelopment of the aortic valve, mitral valve, and LV cavity, and retrograde flow in the aortic arc
