C1QL1, LCN2, IL22RA1, MAMDC2, CILP, ASXL3, CRABP1, and SCUBE3 genes were selected for validation through a customized filtering based on gene expression in thyroid tumours and normal thyroid tissues datasets [17–19], assessed from OncomineTM and in the literature available. Here, IL22RA1 is linked to thyroid tumor.
