mortality/aging
postnatal lethality, incomplete penetrance ( J:79293 )
• 63% of mice survive to P18; most deaths occur prior to P7

reproductive system
decreased primordial germ cell number ( J:115437 )
• moderate numbers of primordial germ cells (PGCs) are seen in genital ridges relative to wild-type and KitlSl-gb homozygotes at E11.5
• at E9.5, PGC numbers in the hindgut are 44% of wild-type
abnormal primordial germ cell migration ( J:115437 )
• at E10.5, 83% of total PGCs have migrated from hindgut, compared to 93% in wild-type
decreased primordial germ cell proliferation ( J:115437 )
• proliferation indices of migratory (in mesentery and genital ridges) and postmigratory PGCs (in genital ridges) at 10.5 and 11.5 are significantly reduced compared to wild-type values (54-66% of wild-type values)

hematopoietic system
low mean erythrocyte cell number ( J:79293 )
• significantly lower than wild-type at birth (41% of wild-type value)
decreased hematocrit ( J:79293 )
• significantly lower than wild-type at P24-25
increased mean corpuscular hemoglobin ( J:79293 )
• significantly increased compared to wild-type at P24-25
increased mean corpuscular hemoglobin concentration ( J:79293 )
• significantly increased compared to wild-type at P24-25

cellular

macrocytic anemia ( J:79293 )
