摘要
Factor XI (FXI) deficiency is an autosomal bleeding disorder of variable severity. Inheritance is not completely recessive as heterozygotes may display a distinct, if mild, bleeding tendency. Eighteen unrelated FXI-deficient patients were screened blind by fluorescent single-stranded conformation polymorphism (F-SSCP) analysis and denaturing high-performance liquid chromatography (dHPLC). Mutations were detected in 14 of the 18 patients (similar to78%) by F-SSCP and in all 18 patients by dHPLC. Dideoxy sequencing confirmed the mutations in all 18 patients: eight of the mutations being novel (four of which were in previously reported patients). This showed dHPLC to be a highly sensitive, reliable technique for mutation screening in heterogeneous disorders.
