It is worth noting that the glucose levels in this study were all within normal range, but it could not rule out the possibility that a relatively higher glucose level within the normal range was resulting from a relatively lower insulin level, which is a growth factor in childhood, and it might be associated to malnutrition or emaciation, which are generally signs of a low level of serum uric acid (20, 32–35). This evidence concerns the gene INS and malnutrition.
