PHYSIOLOGY Genetics of a Coronary Vascular Disorder

The genetic factors influencing coronary artery disease (CAD) remain poorly defined. Wang et al. studied a large family with high incidence of a vascular condition resembling CAD, which in most of the cases led to myocardial infarction. A genome-wide linkage analysis identified an autosomal dominant locus that included MEF2A, an endothelial transcription factor that is thought to participate in vascular development. A deletion-mutation within MEF2A that conferred altered cellular distribution of the protein specifically segregated with genes of family members having the CAD-like vascular condition. It remains to be seen whether the MEF2A pathway plays a role in the common form of CAD resulting from atherosclerosis.
