NOTE: Loss = allele-specific copy loss; Gain = allele-specific copy gain.
↵aThe frequency was calculated from all biopsies from both time points within each patient.
↵bThe average of the sizes of SCA in a chromosome arm surrounding the SCA locations used in prediction models.
↵cBoundaries for each 1-Mb segment follow the standard as in chromosome 1: 36–37, which includes the nucleotides on chromosome 1 from 36,000,001 to 37,000,000 base pairs on human genome reference hg19.
↵dOnly one sample with SCA in this region so no variance in average SCA size can be calculated.
↵eNo samples had SCA spanning this region.
