♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
immune system
increased germinal center B cell number ( J:191090 )
• mutants exhibit an increase in percentage and the total number of germinal center B cells compared to wild-type mice, although the total number of germinal center B cells is lower than in Fcgr2b homozygotes (that are also heterozygous for the floxed Traf3ip2 allele)
glomerulonephritis ( J:191090 )
• develop glomerulonephritis comparable to single Fcgr2b homozygotes

hematopoietic system
increased germinal center B cell number ( J:191090 )
• mutants exhibit an increase in percentage and the total number of germinal center B cells compared to wild-type mice, although the total number of germinal center B cells is lower than in Fcgr2b homozygotes (that are also heterozygous for the floxed Traf3ip2 allele)

renal/urinary system
glomerulonephritis ( J:191090 )
• develop glomerulonephritis comparable to single Fcgr2b homozygotes
