Fig. 6From: Identification of blood-based key biomarker and immune infiltration in Immunoglobulin A nephropathy by comprehensive bioinformatics analysis and a cohort validationqPCR Validation of the expression pattern and evaluation of diagnostic efficacy of 6 clinical correlated genes using our patient cohort. In our cohort, significantly upregulated genes were confirmed on ORMDL2 (A), COL4A1 (B) and NRP1 (C), whereas PKP4 (D) and ST13 (E) were not consistent with the results from datasets. According to the ROC curves (F), the highest AUC could be observed using the gene COL4A1Back to article page
