This fact sheet contains general information. Each person should be referred to a genetic service for further information and advice about what a faulty SDHD gene means for them. 

Key Points

  • People with a faulty SDHD gene who have inherited it from their father have an increased chance of developing paraganglioma and phaeochromocytoma. They also have a small increased chance of developing kidney (renal) cancer and a tumour in the stomach/intestine called a gastrointestinal stromal tumour (GIST).
  • People with a faulty ​SDHD gene who have inherited it from their mother do not have a significantly increased chance of developing paraganglioma, phaeochromocytoma, kidney cancer or GIST. However, they may still pass the faulty gene onto their children.
  • Family members (including children) can be referred to a genetic service where experts can provide information, advice and support about their risk of cancer and the option of genetic testing.
