The lower Hb1Ac (without significant difference in glycemic values) and plasma triglyceride median values observed in the PVV haplotype could be caused by an increase in erythropoiesis [49,50] and higher lipoprotein lipase activity with higher removal rate of triglycerides from blood circulation [51,52,53], respectively, which could result from the prevalence of PVV in hyperthyroidism. This evidence concerns the gene LPL and hyperthyroidism.
