All spontaneous mutant mice with cytoskeletal deficiencies of spectrin reported to date have HS. Here, the first spontaneous mouse mutant,sphDem\/ sphDem, with severe HE is described. The sphDem mutation is the insertion of an intracisternal A particle element in intron 10 of the erythroid \u03b1-spectrin gene. This causes exon skipping, the in-frame deletion of 46 amino acids from repeat 5 of \u03b1-spectrin and alters spectrin dimer\/tetramer stability and osmotic fragility. The disease is more severe insphDem\/sphDem neonates than in \u03b1-spectrin\u2013deficient mice with HS. Thrombosis and infarction are not, as in the HS mice, limited to adults but occur soon after birth. Genetic background differences that exist between HE and HS mice are suspect, along with red blood cell morphology differences, as modifiers of thrombosis timing.sphDem\/sphDem mice provide a unique model for analyzing spectrin dimer- to-tetramer conversion and identifying factors that influence thrombosis.<\/jats:p>","DOI":"10.1182\/blood.v97.2.543","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T12:46:47Z","timestamp":1027774007000},"page":"543-550","update-policy":"http:\/\/dx.doi.org\/10.1182\/blood.2019cm0000","source":"Crossref","is-referenced-by-count":17,"title":["Defective spectrin integrity and neonatal thrombosis in the first mouse model for severe hereditary elliptocytosis"],"prefix":"10.1182","volume":"97","author":[{"given":"Nancy J.","family":"Wandersee","sequence":"first","affiliation":[{"name":"From The Jackson Laboratory, Bar Harbor, ME; the Lawrence Berkeley National Laboratory, University of California-Berkeley, Berkeley, CA; the Division of Molecular Genetics, The Netherlands Cancer Institute, Amsterdam, The Netherlands; and Tufts University School of Veterinary Medicine, Boston, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amanda N.","family":"Roesch","sequence":"additional","affiliation":[{"name":"From The Jackson Laboratory, Bar Harbor, ME; the Lawrence Berkeley National Laboratory, University of California-Berkeley, Berkeley, CA; the Division of Molecular Genetics, The Netherlands Cancer Institute, Amsterdam, The Netherlands; and Tufts University School of Veterinary Medicine, Boston, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nancy R.","family":"Hamblen","sequence":"additional","affiliation":[{"name":"From The Jackson Laboratory, Bar Harbor, ME; the Lawrence Berkeley National Laboratory, University of California-Berkeley, Berkeley, CA; the Division of Molecular Genetics, The Netherlands Cancer Institute, Amsterdam, The Netherlands; and Tufts University School of Veterinary Medicine, Boston, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joost","family":"de Moes","sequence":"additional","affiliation":[{"name":"From The Jackson Laboratory, Bar Harbor, ME; the Lawrence Berkeley National Laboratory, University of California-Berkeley, Berkeley, CA; the Division of Molecular Genetics, The Netherlands Cancer Institute, Amsterdam, The Netherlands; and Tufts University School of Veterinary Medicine, Boston, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin A.","family":"van der Valk","sequence":"additional","affiliation":[{"name":"From The Jackson Laboratory, Bar Harbor, ME; the Lawrence Berkeley National Laboratory, University of California-Berkeley, Berkeley, CA; the Division of Molecular Genetics, The Netherlands Cancer Institute, Amsterdam, The Netherlands; and Tufts University School of Veterinary Medicine, Boston, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roderick T.","family":"Bronson","sequence":"additional","affiliation":[{"name":"From The Jackson Laboratory, Bar Harbor, ME; the Lawrence Berkeley National Laboratory, University of California-Berkeley, Berkeley, CA; the Division of Molecular Genetics, The Netherlands Cancer Institute, Amsterdam, The Netherlands; and Tufts University School of Veterinary Medicine, Boston, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
