G6PD gene detection in neonatal hyperbilirubinemia and analysis of related risk factors

Insights

Neonatal hyperbilirubinemia is linked to Glucose-6-phosphate dehydrogenase (G6PD) gene mutations, specifically G1388A and G1376T. Early detection and management of risk factors like prematurity and infection are crucial for prevention.

Area of Science:

  • Neonatal Medicine
  • Medical Genetics
  • Pediatrics

Background:

  • Neonatal hyperbilirubinemia is a common condition, particularly in premature infants.
  • Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a known risk factor.

Purpose of the Study:

  • To determine the incidence of G6PD deficiency in neonates with hyperbilirubinemia.
  • To analyze the genetic etiologies of G6PD deficiency in this population.
  • To provide evidence for clinical diagnosis and treatment.

Main Methods:

  • Gene detection for G6PD mutations in 64 neonates with hyperbilirubinemia and 30 controls.
  • Multivariate logistic regression analysis to identify risk factors.

Main Results:

  • G1388A (92.19%) and G1376T (7.81%) mutations were found in neonates with hyperbilirubinemia, not in controls.
  • Prematurity, artificial feeding, delayed feeding initiation, delayed first bowel movement, premature rupture of membranes, infection, scalp hematoma, and perinatal asphyxia were significant risk factors.

Conclusions:

  • G1338A and G1376T mutations are key genetic features of neonatal hyperbilirubinemia.
  • Genetic detection combined with prevention of identified risk factors can reduce disease incidence.
