phenotypes
All mutations/alleles(4) : Targeted(4)
Genomic Mutations involving Itga2b (1)
Incidental mutations (data from Mutagenetix , APF , CvDC )
 
Homozygotes for targeted null mutations exhibit a bleeding disorder, lack platelet binding to fibrinogen, absence of fibrinogen in platelet alpha granules, and increased numbers of hematopoietic progenitors in yolk sac, fetal liver, and bone marrow.
