ABSTRACT
OBJECTIVE@#To analyze the clinical phenotype and genetic basis of a consanguineous pedigree affected with hereditary coagulation factor XII (FXII) deficiency.@*METHODS@#Following extraction of genomic DNA, all exons and flanking regions of F12 gene were subjected to PCR amplification and Sanger sequencing. ClustalX-2.1-win and MutationTaster software was used to analyze the conservation and impact of the variants on protein function.@*RESULTS@#DNA sequencing showed that the proband carried a homozygous g.6753-6755delACA deletion (p.252delAsn) in exon 9 of the F12 gene, for which her father, mother and brother were heterozygous carriers. The same deletion was not found in her sister.@*CONCLUSION@#The homozygous p.252delAsn deletion probably underlies the hereditary FXII deficiency in this pedigree.
