• unlike Rad50tm2Jpt homozygotes, mice do not exhibit increased lethality or anemia at 8 months

cellular
decreased apoptosis ( J:129762 )
• attrition of B-, T- and myeloid cell lineages, gut and seminiferous tubules observed in Rad50tm2Jpt homozygotes is mitigated

hematopoietic system
anemia ( J:129762 )
• compared to Rad50tm2Jpt homozygotes, the age of onset of anemia is reduced
