ABSTRACT
<p><b>OBJECTIVE</b>To identify the phenotype and genotype in four Chinese pedigrees with inherited coagulation factor V (FV) deficiency.</p><p><b>METHODS</b>The tests of activated partial thromboplastin time (APTT), prothrombin time (PT), FV activity (FVC) and FV antigen (FVAg) were used for phenotype diagnosis. All the exons and exon-intron boundaries of F5 gene were amplified by PCR and analyzed by direct sequencing.</p><p><b>RESULTS</b>The APTT and PT in each of the four probands were obviously prolonged, and both activity and antigen of FV in the four probands were extremely lower compared with that of normal mixed plasma. Sequencing of F5 gene in proband 1 identified a heterozygous mutation, G16088C (Asp68His), and four polymorphisms, T35788C (Met385Thr), A47295G (His1299Arg), A58668G (Met1736Val) and A74083G (Asp2194Gly), which were located in the same chromosome; proband 2 was homozygous for two mutations, C46253T (Arg952Cys) and C46724T(Gln1109stop); the F5 gene of proband 3 showed a homozygous missense mutation, C67793G(Pro2006Ala); and proband 4 was homozygous for one missense mutation, C74022T (Arg2174Cys).</p><p><b>CONCLUSION</b>Five mutations (Asp68His, Arg952Cys, Gln1109stop, Pro2006Ala and Arg2174Cys) and four polymorphisms (Met385Thr, His1299Arg, Met1736Val and Asp2194Gly) may lead to type I inherited FV deficiency for these four probands, respectively. Gln1109stop, Pro2006Ala and Arg2174Cys haven't been identified before.</p>
