IGF2 and neoplasm: Twelve tumours showed CN gains (0.6 < log2(ratio) < 0.9) below the threshold used for defining amplification (log2(ratio) ≥ 1) and might indicate a subgroup of tumours harbouring sub‐clonal amplifications of IGF1R. The two remaining variations were CN losses of IGF2 and IGFBP6. Interestingly, the amplitude of the SCNVs correlated inversely with its size (Table 1).
