A female neonate born to a 21-year-old G2P1 had jaundice at 8 hours of life. The neonate’s red blood cell type was  A+, while the mother’s RBC type was O+. The mother’s anti-A antibody titer was elevated. A screen for a fetomaternal bleed was negative. The direct Coombs test was weakly positive. The infant’s hemoglobin and total bilirubin were 10.6g/dL and 7 mg/dL, respectively. The erythrocyte glucose-6-phosphate was normal and the sickle cell test was negative. A peripheral blood smear showed normocytic normochromic RBCs, nucleated RBCs, and reticulocytes. What is the most likely diagnosis?
