hematopoietic system
decreased eosinophil cell number ( J:198489 )
• peripheral blood is deficient in eosinophils relative to wild-type (0.19% vs 1.85%)
• other non-eosinophilic circulating cell populations are unchanged in cell number and relative composition in mutants

immune system
decreased eosinophil cell number ( J:198489 )
• peripheral blood is deficient in eosinophils relative to wild-type (0.19% vs 1.85%)
• other non-eosinophilic circulating cell populations are unchanged in cell number and relative composition in mutants
