immune system
increased IgG1 level ( J:165408 )
• Background Sensitivity: enhanced primary and secondary responses to NP16CGC immunization, however author speculates that the enhanced antibody response may be due to a SNP of 129 origin in the Fcgr2b promoter.
increased anti-nuclear antigen antibody level ( J:165408 )
• Background Sensitivity: a marginal increase in ANAs compared to C57BL/6 mice however C57BL/6 mice consomic for similar region of chromsomome 1 have a similar increase in ANAs

hematopoietic system
increased IgG1 level ( J:165408 )
• Background Sensitivity: enhanced primary and secondary responses to NP16CGC immunization, however author speculates that the enhanced antibody response may be due to a SNP of 129 origin in the Fcgr2b promoter.
