At a return appointment 44 hours later, her total serum bilirubin was 41.7 mg\/dL and signs of acute kernicterus were present. Maternal\/fetal blood group O\/B incompatibility was identified, with a negative direct antiglobulin test, which was positive on retesting. She had abundant spherocytes on blood smear, and these persisted at follow-up, but neither parent had spherocytes identified. A heterozygous SLC4A1E508K mutation (gene encoding erythrocyte membrane protein band 3) was found, and in silico predicted to result in damaged erythrocyte cytoskeletal protein function. No mutations were identified in other red cell cytoskeleton genes (ANK1, SPTA1, SPTB, EPB41, EPB42) and the UGT1A1 promoter region was normal. Neurologic follow-up at 2 and 4 months showed developmental delays consistent with mild kernicterus.<\/jats:p>","DOI":"10.1542\/peds.2012-3799","type":"journal-article","created":{"date-parts":[[2013,7,23]],"date-time":"2013-07-23T01:32:36Z","timestamp":1374543156000},"page":"e531-e534","source":"Crossref","is-referenced-by-count":15,"title":["Acute Kernicterus in a Neonate With O\/B Blood Group Incompatibility and a Mutation in <i>SLC4A1<\/i>"],"prefix":"10.1542","volume":"132","author":[{"given":"Robert D.","family":"Christensen","sequence":"first","affiliation":[{"name":"Women and Newborns Program, Intermountain Healthcare, Salt Lake City, Utah;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hassan M.","family":"Yaish","sequence":"additional","affiliation":[{"name":"Division of Hematology\/Oncology, Department of Pediatrics,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto H.","family":"Nussenzveig","sequence":"additional","affiliation":[{"name":"Department of Pathology, and"},{"name":"ARUP Laboratories, Salt Lake City, Utah"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.
