Potential biomarkers of FRDA: gene associations to clinical data based on differential expression.

n = significant genes; selected categories and their genes are displayed. Frataxin levels, Age of Diagnosis, ICARS1; n = genes found by EPIG analysis. ICARS2; n = genes found by supervised correlation analysis, where the r and P values between gene expression and ICARS score were calculated. BP = Gene ontology system, biological process. CC = Gene ontology system, cellular component. MF = Gene ontology system, molecular function.
