A 32-year-old G2P1 patient with an O-negative blood type presents for a prenatal consultation. Her medical history reveals that during her previous pregnancy with an Rh-positive fetus, she experienced a small placental abruption and failed to receive prophylactic anti-D immune globulin (RhoGAM). If maternal alloimmunization occurred and these specific IgG antibodies cross the placenta during her current pregnancy, the fetus is at highest risk for developing which of the following conditions?
