These results differ from what is seen in the controls, in which we showed that PTH levels in children were 25.23 ± 9.10 pg/mL and 26.87 ± 8.57 pg/mL in adolescents; a statistical difference between DS individuals and controls was seen in children (P < 0.0001) but not in adolescents. This evidence concerns the gene PTH and Dravet syndrome.
