Hemophilia A is an X-linked bleeding disease caused by mutations in the coagulation factor VIII gene. The identification and characterization of pathogenic mutations allows the recognition of new mechanisms of functional disturbances of factor VIII. To screen for mutations exons 1-26 of the factor V

✦ Synopsis
In this study we have analyzed the factor IX gene from 84 hemophilia B patients of Spanish origin. It included single-strand conformation polymorphism (SSCP) analysis of all functional regions of the gene and further sequencing of all fragments showing abnormal migration. In 76 patients (90.4%), it was possible to identify molecular alterations leading to the appearance of the disease. Twenty-one new mutations were identified, including 13 missense mutations, two nonsense mutations, three splice-site mutations, one frameshift deletion, one frameshift insertion, and one nonframeshift deletion. The approach appears to be very suitable for molecular diagnosis of hemophilia B. Hum Mutat 13:160165, 1999.

The coding region of Cx32 was amplified by touchdown polymerase chain reaction (PCR) (Don et al., 1991). Three primer sets were used corresponding to nucleotides 54-77 (CX32-1) and 336-359 (CX32-2), i.e., part 1, 273-269 (Cx32-3) and 685-704 (Cx32-5), i.e., part 2, and 635-658 (Cx32-S1) and 919-938
To detect mutations in the thiopurine S-methyltransferase gene (TPMT), we have developed a strategy based on single-strand conformation polymorphism (SSCP) analysis of the gene amplified by polymerase chain reaction (PCR). The sensitivity of the method was first evaluated by analyzing DNA samples fr
