Germline mutations in at least 25 different genes have been reported to predispose to PC/PGL/HNPGL or RCC (NF1, RET, MAX, EGLN1, EGLN2, MSH2, KIFIB, SDHAF2,MEN1, BAP1, CDC73, CDKN2B, FLCN, MET, PBRM1, PTEN, TSC1, TSC2, FH, SDHA, SDHB, SDHC, SDHD, TMEM127, and VHL) (6–9, 12–14, 15). This evidence concerns the gene MAX and renal cell carcinoma.
