We also analyzed the association between BMAL1 gene polymorphisms and blood glucose level in children with different glucose status (normal blood glucose and prediabetes/diabetes), and neither in normal blood glucose group nor in children with prediabetes/diabetes participants significant association between the four SNPs of BMAL1 and blood glucose level was found (P > 0.05, Table S3). The gene discussed is BMAL1; the disease is diabetes mellitus.
