♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
immune system
increased mature B cell number ( J:139293 )
• the number of mature peripheral B cells is increased resulting enlargement of the spleen and lymph nodes
• however, B cell proliferation is normal

hematopoietic system
increased mature B cell number ( J:139293 )
• the number of mature peripheral B cells is increased resulting enlargement of the spleen and lymph nodes
• however, B cell proliferation is normal

growth/size/body
enlarged spleen ( J:139293 )
