THE RELATIVE EFFICACY OF GENETIC ANALYSIS AND COAGULATION TESTING IN THE DIAGNOSIS OF CARRIERS OF HEMOPHILIA A

This study has assessed the relative benefits of restriction fragment length polymorphism (RFLP) linkage and coagulation testing in the diagnosis of carriers of hemophilia A. 221 samples from 55 families have been studied for intragenic and flanking RFLPs. All samples were tested for the Factor VIII intragenic Bell RFLP and for the flanking marker St 14. 83% of obligate carrier females were heterozygous at oneor both of these two …
