| Abstract_FL | Objective To analyze the clinical and laboratory abnormalities of two patients with α1-antitrypsin (α1-AT) Pittsburgh in a family and review the literatures.Methods Both plasma clotting time and factor activities were performed using clotting or substrate methods.Platelet aggregation was evaluated using an optical aggregometer.The serum protein electrophoresis was performed on Sebia HYDRASYS by using Agarose gel.The exons of αl-AT were amplified by using polymerase chain reaction (PCR) and then sequenced and compared with NCBI GenBank records.Results The proband had several ruptures of corpus luteum and bleeding after operation,while her daughter had no bleeding history.Both of them showed prolonged coagulation tests which could not be corrected by mixing with the normal plasma.They also showed low levels of plasma coagulation factors,undetected protein C and S activity and abnormal bands of α1-globulin.The results of gene sequencing demonstrated that they were heterozygous for g.T17132G (p.Met358Arg) mutation of α1-antitrypsin gene (NG_008290.1).Conclusions Comparing with the data of previously reported cases,our results confirmed the obvious abnormality of coagulation test and the discrepancy of bleeding tendency of α1-antitrypsin Pittsburgh patients,and suggested that the rupture of corpus luteum would be a specific characteristic in women of child-bearing age. |
