INS and neoplasm: As predicted, KCNQ1OT1 (FDR p = 0.0046) and KCNQ1 (FDR p = 0.0046) were found to have perturbation of allele-specific expression in tumor samples with 11p15.5 LOH, but not ROI or LOI, while INS-IGF2 and IGF2 showed perturbation of allele-specific expression in both samples with 11p15.5 LOH and LOI.
