Position of the tumours according to the results of the genetic analysis
| Total | Hereditary proven disease (%) | Sporadic disease (%) | Disease associated with not clearly deleterious mutations of SDHs | p value | Phaeo or Pgl associated with VHL | Phaeo or Pgl associated with RET | Tumours associated with SDHs | |
|---|---|---|---|---|---|---|---|---|
| The p values (Fisher’s test) are for the comparison between hereditary disease with sporadic disease. | ||||||||
