The S120 locus within the KH_1 domain of FUBP1 demonstrated a high phosphorylation level in primary tissues of lung adenocarcinoma (p = 0.03978) and clear cell renal carcinoma (p = 0.01431) compared with control tissues and in pediatric brain cancer in Asian children compared with Caucasian children (p = 0.003247). The gene discussed is FUBP1; the disease is lung adenocarcinoma.
