In 1988, we reported a thrombasthenic patient whose platelets contained an abnormal molecular weight GPIIb (Blood, 71, 915, 1988). Here we describe another patient whose platelets contain a variant GPIIb with properties similar to the previously reported abnormal GPIIb. This patient has a small amount of the abnormal GPIIb and was suggested to be a heterozygote characterized by deficient and abnormal GPIIb genes. The abnormal GPIIb was suggested to be related to the precursor form of GPIIb because the molecular weights of both proteins are the same. The abnormal GPIIb may lack a peptide region around the cleavage site of the two chains, as suggested from its lack of reactivity towards antibodies against these epitopes.
