Hemophilia A is an inherited X-linked bleeding disorder caused by a deficiency of coagulation FVIII, characterized by spontaneous or post-traumatic bleeding episodes, which can lead to physical incapacitation due to arthropathy and even death. The deficiency is the result of mutations on F8 gene. Diagnosis of Hemophilia A carrier status is important for genetic counseling as well as to provide treatment for symptomatic carriers, which, in most cases, are unaware of the fact. In this work, we intend to create the necessary methodology for the molecular identification of hemophilia A carriers, based on the analysis of 26 diagnosed patients, enrolled in the Centro de Hemoterapia e Hematologia do Pará, and their consanguineous relatives, likely carriers of the allele. The control group consisted of 110 males of the population of Belém. The research was based on analyzes of six STRs (Short Tandem Repeats) located in the 3' end region of the gene F8: CTT3, TAAA3, TTTA3, DXS10011, DXS7423, GATA31E08. The use of the six markers proved to be useful in the identification and in the exclusion of the carriers, and all the obligatory carriers were identified. This identification protocol can be routinely used to identify hemophilia A carriers and to provide genetic counseling in these women.
