[Molecular Biological Mechanism and Transfusion Strategy of a Jk(a-b-) Family].

OBJECTIVE: high frequency antigen antibody and her eight family members. METHODS: gene were sequenced by Sanger method. RESULTS: antibodies, the hospital formulated a number of blood preparation strategies for the patient and she was discharged after recovery. CONCLUSION: (c.499A>G,c.588A>G) may be a new genetic pattern leading to the weakening of Kidd antigenicity, which lays a foundation for the study of population genetics.
