A variety of factor VIII (for hemophilia A) or factor IX (for hemophilia B) intragenic polymorphic sites are screened after PCR amplification (Thompson, 1991; Thompson, 2000). Tests are informative if linkage of the hemophilic mutation or phenotype can be established and can be used for carrier detection or prenatal diagnosis. This test is performed pursuant to a license agreement with Roche Molecular Systems, Inc.
