ABSTRACT
<p><b>OBJECTIVE</b>To explore the association of the glycophorin A(GPA) gene mutation in peripheral erythrocytes and chronic benzene poisoning.</p><p><b>METHODS</b>Sixty-three patients with chronic benzene poisonings and 45 benzene-exposed workers who were engaged in the same job title were investigated. Fluorescence immunolabeling technique and flow cytometry were used to detect GPA mutation frequency in peripheral read blood cell.</p><p><b>RESULTS</b>A significant decrease in WBC count and neutrophil count was found in patients with chronic benzene poisoning compared with control individuals (P<0.01). The WBC count and neutrophil count both decreased along with the GPA-NN frequency, and the trends were significant(P<0.05).Both WBC counts and neutrophil counts decreased as the frequency, and trends were significant(P<0.05). GPA-NN frequency increased along with the accumulative exposure score, and the trend was significant (P = 0.0026). There was no significant trend between the GPA-Nphi frequency and the accumulative exposure score (P = 0.2037).</p><p><b>CONCLUSION</b>A decrease in WBC count and neutrophil count is found in patients with chronic benzene poisoning, which can arise from genetic damage in bone marrow stem cells, namely gene-duplicating mutations (NN) at the GPA locus in bone marrow cells of MN-heterozygous subjects, GPA-NN mutagens contributed to the pathogenesis of chronic benzene poisoning.</p>
