Summary

Cigarette smoking is a well-recognized risk factor of Graves' disease and, particularly, Graves' ophthalmopathy. Hence, germline polymorphisms of detoxification genes and genes belonging to the major DNA repair/apoptosis pathways might have an important role in disease susceptibility. In addition, as some of these genes are regulated by thyroid hormones, they could affect the outcome of these patients. Our objective was to assess the influence of the GST, CYP and TP53 gene polymorphisms in the risk of Graves' disease and its outcome.

Detailed description

Although the role of many polymorphisms of genes related to toxins' metabolism has been extensively investigated regarding the susceptibility to thyroid cancer, their influence in thyroid autoimmune diseases risk is still largely unknown. Hence, this study was designed to assess the influence of GSTT1, GSTM1, GSTP1, CYP1A1 and 72TP53 polymorphic inheritance on the susceptibility to Graves' disease and to its response to the treatment.
