In this study, a Lebanese woman with severe factor XI deficiency as well as several unaffected family members were analysed. The F1 1 gene was screened by polymerase chain reaction amplification of all 15 exons, including intron-exon junctions followed by single-strand conformational analysis. Variant single-strand conformational analysis profiles were obtained for exon 13; sequencing of these products allowed the identification of a novel missense mutation (Trp501Cys) situated in the catalytic domain, in homozygosity in the proband.
