How is heart disease passed down genetically?
Most genetic heart conditions are inherited in an autosomal dominant pattern. Autosomal means that both men and women are equally affected. Dominant means that although there are two copies of each gene, a mutation in just one copy is enough to cause disease.
What genes cause coronary heart disease?
Further molecular genetic studies established MEF2A as the gene causing CAD and MI in the family, and a 21-basepair deletion was identified in the last exon of MEF2A (exon 11) in all affected members in the family but not in the family members with normal phenotypes or in 119 individuals with normal angiograms [25].
How do genetics contribute to CAD?
For CAD as well as other common polygenic disorders, multiple genetic risk variants are inherited by everyone. Those at high genetic risk for CAD have a greater genetic risk burden due to inheritance of a greater number of common risk variants, as opposed to inheriting one or more genetic variant of high risk.
Are blocked arteries hereditary?
The genetic family ties that bind brothers and sisters also link their risk for developing clogged arteries and having potentially fatal heart attacks, scientists at Johns Hopkins report. And according to researchers, brothers bear the brunt of the burden.

The most accurate method to detect blocked arteries remains an invasive test called cardiac angiography, which requires a catheter to be threaded into heart vessels.
