Wang found that LDHD genes expression was considered to be a favorable predictive of the prognosis (OS) of ccRCC patients from TCGA (n = 509) and Fudan University Shanghai Cancer Centre (FUSCC, n = 192) cohorts, which indicated LDHD might be involved in ccRCC pathogenesis (Wang et al., 2018). This evidence concerns the gene LDHD and nonpapillary renal cell carcinoma.
