Lack of association between the glutathione-s-transferase genes (GSTT1 and GSTM1) and nasal polyposis.

OBJECTIVES To evaluate the glutation-S-transferase (GST) polymorphisms (GSTM1 and GSTT1) in nasal polyposis (NP). METHODS The study population consisted of 102 unrelated healthy individuals and 98 patients with NP (67 without asthma, 31 with asthma). Genotyping of the polymorphism in the GSTM1 and GSTT1 genes was performed using the multiplex polymerase… CONTINUE READING
