Abstract

Myocardial infarction, a leading cause of death in the Western world1, usually occurs when the fibrous cap overlying an atherosclerotic plaque in a coronary artery ruptures. The resulting exposure of blood to the atherosclerotic material then triggers thrombus formation, which occludes the artery2. The importance of genetic predisposition to coronary artery disease and myocardial infarction is best documented by the predictive value of a positive family history3. Next-generation sequencing in families with several affected individuals has revolutionized mutation identification4. Here we report the segregation of two private, heterozygous mutations in two functionally related genes, GUCY1A3 (p.Leu163Phefs*24) and CCT7 (p.Ser525Leu), in an extended myocardial infarction family. GUCY1A3 encodes the α1 subunit of soluble guanylyl cyclase (α1-sGC)5, and CCT7 encodes CCTη, a member of the tailless complex polypeptide 1 ring complex6, which, among other functions, stabilizes soluble guanylyl cyclase. After stimulation with nitric oxide, soluble guanylyl cyclase generates cGMP, which induces vasodilation and inhibits platelet activation7. We demonstrate in vitro that mutations in both GUCY1A3 and CCT7 severely reduce α1-sGC as well as β1-sGC protein content, and impair soluble guanylyl cyclase activity. Moreover, platelets from digenic mutation carriers contained less soluble guanylyl cyclase protein and consequently displayed reduced nitric-oxide-induced cGMP formation. Mice deficient in α1-sGC protein displayed accelerated thrombus formation in the microcirculation after local trauma. Starting with a severely affected family, we have identified a link between impaired soluble-guanylyl-cyclase-dependent nitric oxide signalling and myocardial infarction risk, possibly through accelerated thrombus formation. Reversing this defect may provide a new therapeutic target for reducing the risk of myocardial infarction.

    Thrombus formation in arterioles in vivo

    An arteriole in cremaster-microcirculation with a diameter of about 40 µm. Blood flow is from bottom to top, the animal has received high molecular weight FITC-dextran intravenously which is photoexcited by illuminating the preparation at 450-490nm using mercury lamp at time point 01:07:00. This is visible as a light spot in arteriole, which reflects the excitation of the dye. Thrombus formation starts to be visible downstream of the excitated area in the upper right corner 42 s later. Thereafter, flow decelerates and comes to complete stop 88 s after starting the photoexcitation, which is turned-off at this point.
