TBX1 and coronary artery disorder: To elucidate how TBX1 target genes may be implicated in the CHD WES data set, we utilized data from gene expression microarrays to analyze human homologs of genes differentially expressed in microdissected cardiac progenitor tissues expressed between Tbx1 knock-out mouse embryo and normal embryo at three different embryonic days–E8.5, E9.5, and E10.5 [37].
