Red Blood Cell Membrane-Related Gene Variants and Clinical Risk Factors in Chinese Neonates with Hyperbilirubinemia.

Introduction: Neonatal hyperbilirubinemia is common and remains a clinical concern in China. Since neonatal hyperbilirubinemia is linked to genetic factors, we aimed to identify the gene variants of the red blood cell membrane (RBCM) and evaluate the clinical risk factors in Chinese neonates with hyperbilirubinemia.

Methods: 117 hyperbilirubinemia neonates (33 cases of moderate hyperbilirubinemia and 84 cases of severe hyperbilirubinemia) and 49 controls with normal bilirubin levels were selected as our study subjects.
