Genetic basis of congenital platelet disorders

Abstract

Over the past 4 decades, a better understanding of the genetic origins of inherited platelet disorders has illuminated avenues of investigation in megakaryopoiesis and has identified targets of pharmacologic intervention. Many of these discoveries have been translated into clinical medicine. The success of inherited platelet disorder research is underpinned by broader advances in methodology through the biochemical and molecular revolution of the 20th and 21st centuries, respectively. Recently, modern genomics techniques have affected platelet and platelet disorders research, allowing for the discovery of several genes involved in platelet production and function and for a deeper understanding of the RNA and miRNA networks that govern platelet function. In this short review, we focus on recent developments in the genetic elucidation of several disorders of platelet number and in the molecular architecture that determines the "genetic makeup" of a platelet in health and disease.
