In addition to patients with RAPTAS, separate case reports of PC/PGL/HNPGL or renal tumors have been reported in association with the six genes described in Table 3, as well as with mutations in FH (14, 21) and SDHA (9, 22) (although no cases of coexisting PC/PGL and RCC in the same patient had been reported in conjunction with a mutation in FH/SDHA). This evidence concerns the gene SDHA and pachyonychia congenita.
