Yc. Piao et al., ARG578GLN MUTATIONS IN THE VON-WILLEBRAND-FACTOR GENE IN 3 UNRELATED CASES OF TYPE-IIB VON-WILLEBRAND DISEASE, Blood coagulation & fibrinolysis, 4(5), 1993, pp. 787-789
A recurrent heterozygous CGG-->CAG (Arg578Gln) mutation was detected i
n exon 28 of the von Willebrand factor gene in three additional unrela
ted families with inherited type IIB von Willebrand disease. This iden
