We report a Caucasian neonate with chronic non-spherocytic hemolytic anemia due to a class I G6PD deficiency. A novel mutation missense mutation in exon eight of the G6PD gene was detected (c.827C>T p.Pro276Leu). Bilirubin peaked on day 5 at 24 mg/dl with a conjugated bilirubin of 17 mg/dl. Jaundice resolved within 4 weeks. A detailed work-up failed to reveal other specific factors contributing to cholestasis. Severe hemolytic disease of the newborn may cause cholestasis even in the absence of associated primary hepato-biliary disease. Pediatr Blood Cancer. (c) 2010 Wiley-Liss, Inc.
