We found two CpGs in the GRN vs. CTRL comparison (cg24203376 within the TDRD1 gene and cg05726248 within the TESPA1 gene) and one CpG common to both comparisons of sporadic FTD patients versus healthy controls (cg12150421 within the KIF17 gene). This evidence concerns the gene TESPA1 and frontotemporal dementia.
