Abstract
A mutation induced by ethylnitrosourea in a spermatogonial stem cell of a 101/H mouse has resulted in a structurally altered beta-diffuse major globin in one of his offspring. The mutant hemoglobin is associated with polycythemia, rubor, increased oxygen affinity and decreased hem-hem interaction. The mutant haplotype has been designated Hbbd4, polycythemia. Amino acid analysis of the mutant globin has shown that a single substitution beta 145 Tyr----Cys has occurred, and it is proposed that ethylnitrosourea induced an A----G transition in the tyrosine codon (TAC----TGC). This murine polycythemia is homologous with hemoglobin Rainier in man, in which the amino acid substitution is also beta 145 Tyr----Cys and which is associated with similar physiological consequences.Entities:
