ROH indicates retention of heterozygosity (ie, heterozygosity with a balanced representation of the 2 alleles); LOH, loss of heterozygosity; H, homozygous; Tel, telomere; Cent, centromere; and MRD, minimal region of deletion. Regional status is indicated as follows: white square, ROH; light grey square, LOH; dark grey square, homozygous deletion; hatched square, undefined status. On the top is the approximate location of genes in relation to the markers. Double vertical lines correspond to the boundaries of the minimal region of deletion. *Results previously reported.¹¹
