IGFBP2 and post-traumatic stress disorder: Three NDD CNV were significantly associated with increased PTSD symptoms, the 2q13 deletion (chr2:111,394,040–112,012,649, N = 15 carriers, beta = 0.1455, SE = 0.0367, p = 0.0001, q = 0.0027; OR = 2.508, 95%CI = [0.956,6.583]), the 15q11.2 BP1‐BP2 microdeletion (chr15:22,805,313–23,094,530, N = 529 carriers, beta = 0.0206, SE = 0.0056, p = 0.0002, q = 0.0027; OR = 1.275, 95%CI = [1.093,1.488]), and the 16p11.2 deletion (N = 16 carriers, beta = 0.0702, SE = 0.025, p = 0.0041, q = 0.0369; OR = 2.619, 95%CI = [1.019,6.728]) (Fig. 2).
