Abstract

fetched live from OpenAlex

The prevalence of type 2 diabetes in the Oji-Cree of Northern Ontario is among the highest of any population in the world. We previously demonstrated that markers D8S264 and D22S683 were both linked and associated with type 2 diabetes in the Oji-Cree. Among the possible candidate genes for type 2 diabetes and related traits on chromosomes 8p and 22q were NAT2 and CYP2D6, respectively. We thus explored the possible association of NAT2 and CYP2D6 alleles and diabetes-related traits in a sample of 112 Oji-Cree subjects with type 2 diabetes and 481 Oji-Cree subjects without type 2 diabetes. We found no difference in the allele and genotype frequencies of the NAT2 G191A, C282T, C481T, G590A, A803G and G857A, and the CYP2D6 G1934A polymorphisms between Oji-Cree subjects with and without type 2 diabetes. However, we found a significant association between the NAT2 C282T polymorphism and plasma fasting glucose concentration. Specifically, NAT2 282T/T homozygotes had significantly higher plasma fasting glucose than 282C/C homozygotes, and heterozygotes had intermediate levels of this trait. Thus, variation in NAT2 or CYP2D6 was not associated with the presence of type 2 diabetes, and would not be causative for this phenotype in Oji-Cree. However, NAT2 might be a 'modifier gene' affecting the level of glycaemia in non-diabetic subjects.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
