IL10RB and Dravet syndrome: Based on these observations, we analyzed the frequencies of IFNAR2 rs2229207, IFNGR2 rs2834213, IL10RB rs2834167 and VEGFA rs3025039 SNPs in a group of young adults withDS compared to a group of healthy subjects, matched for age and gender, in order to evaluate whether these polymorphisms can influence the susceptibility of patients with DS to either CHDs or acquired defects.
