ELOVL2 and neoplasm: Furthermore, at the transcriptional level, high-level ELOVL2 expression also significantly correlated with established clinical and molecular markers for favorable tumor biology, including INSS 1, 2 or 4S stage disease (Fig. 4k), Single-copy MYCN status (Fig. 4l), age at diagnosis ≤18 months (Fig. 4m), a low-risk tumor transcriptional profile defined by principal access method (PAM) analysis (Fig. 4n) and favorable Shimada/INPC tumor histology (Fig. 4o).
