Platelet Phenotype Prediction From Whole Genome Sequencing In 621 Sickle Cell Disease Patients

Introduction: Patients with sickle cell disease (SCD) are at increased risk of alloimmunization. Platelet refractoriness is a serious known complication and often seen in SCD patients who are heavily transfused and/or in the bone marrow transplantation (BMT) setting. Next generation sequencing (NGS) is an emerging and promising genotyping strategy in the context of blood typing, due its high throughput and its ability to detect both known and novel variants in the patient and donor population. Here we describe an algorithm to predict common and rare human platelet antigens (HPA) from NGS data, and its validation through Sanger sequencing.
