ABSTRACT
<p><b>OBJECTIVE</b>To analyze the expressed mRNA of the factor subunit A (FA) in monocyte in a hereditary factor (F) deficiency family.</p><p><b>METHODS</b>The F A mRNA of the proband and the other family members was analyzed by RT-PCR, semi-quantitative RT-PCR, cloning and sequencing. The three dimensional structure of the protein was predicted by SWISS-MODEL and viewed by RASMIOL.</p><p><b>RESULTS</b>(1) A large in frame deletion from codons 11 to 279, spanning from exon 2 to 7 of F A (DelCD11-279), was identified in the proband at mRNA level and a truncated protein is predicted composed of 464 amino acids. Compared with the normal and the other families, the proband showed lower level of F A mRNA in RT-PCR. (2) SWISS-MODEL analysis showed that the truncated protein lacked the β-sandwich and a part of catalytic core, resulting in loss of the normal catalytic domains.</p><p><b>CONCLUSION</b>DelCD11-279 of F A mRNA is associated with hereditary F deficiency. The reduced expressing level of F A gene is one of the causes resulting in F deficiency in the patients.</p>
