Platelet receptor gene Ibα-5T/C Kozak polymorphism may influence the risk of MI, concludes a preliminary UK study. In the prelude to MI platelets attach, through a glycoprotein complex GPIb/IX/V, to von Willebrand factor on plaques in the arterial walls. Four subunits (GPIbα, GPIbβ, GPIX, GPV) comprise the receptor …
