Events classified as “whole chromosome” from the combined dataset span an entire chromosome, “telomeric p” and “telomeric q” are events that include the telomere on the p or q arm, respectively, “interstitial” events do not include a telomere or centromere, and “spans centromere” indicates interstitial events that overlap a chromosome’s centromere. Event counts are indicated in parentheses (row percent, column percent).
