HMGA1P4 showed no significant difference in expression between tumour and normal paired samples in any of the validation sets (p > 0.05 in both), whereas RNF139-AS1 showed insignificant expression difference in the technical validation set (p = 0.325) and borderline difference in the biological validation set (p = 0.03). This evidence concerns the gene HMGA1P4 and neoplasm.
