In the article titled “Association of Nuclear Factor-Erythroid 2-Related Factor 2, Thioredoxin Interacting Protein, and Heme Oxygenase-1 Gene Polymorphisms with Diabetes and Obesity in Mexican Patients,” [1] typing errors were found after subsequent analyses of the entire dataset. These issues were raised to the attention of the original authors by Drs. Meza-Espinoza, Leal-Ugarte, and Peralta-Leal of the Universidad Autónoma de Tamaulipas. The allelic frequencies were added and the corrected data are shown in italics in Tables 2, 3, and 4.

Table 2 
Genotype and allele frequencies of the polymorphisms studied in diabetic patients and controls.
Table 3 
Genotype and allele frequencies of the polymorphisms studied in obese and nonobese subjects.
Table 4 
Genotype frequency of the rs7211 polymorphism in subjects without diabetes and women.

It is important to remark that the model (recessive for allele T, Table 4) was calculated taking in count that CC + CT = 0. When CC is considered as the risk allele the OR increases to 2.4 (CI: 1.28–4.64, ) under a dominant model (CC + CT = 1 versus TT = 0). This reveals that the TT genotype in this study shows a protective factor against obesity and the genotype CC could be considered as the risk factor for obesity, as was stated in the original article.

The last paragraph of Section should be “CC carriers had higher glucose levels in comparison with CA + carriers when genotype was compared as dominant model.”

Finally, in Section (Discussion) when Wang et al. [] is cited, the correct statement is the following:

“Individuals with CC genotype had lower total antioxidant capacity, glutathione levels, superoxide dismutase, catalase, and glutathione peroxidase activities as well as lower homeostasis model assessment of -cell function index (HOMA-) in comparison with individuals with the AA genotype.”
