Dup15q syndrome by duplication type. a Spectral profiles of isodicentric (orange) and interstitial (green) duplications. PSDs are averaged across channels and participants; colored highlights represent 95% confidence intervals. Both duplication types show prominent spectral peaks in the beta band (group-level averages: isodicentric, f = 23.2 Hz; interstitial, f = 23.1 Hz). Power does not differ between duplication types (p > 0.05, all frequencies). b Mean topographic scalp power of participants with isodicentric duplications at f = 23.1 Hz (i.e., the Dup15q syndrome spline-interpolated peak frequency). c Mean topographic scalp power of all participants with interstitial duplications at f = 23.1 Hz. d Isodicentric versus interstitial power difference effect sizes (Cohen’s d) at f = 23.1 Hz. Mean effect size across channel, d = 0.21 (min, d = -0.19; max, d = 0.50)
