|---|---|---|
Digestive system | 6 | Neoplasm of the gastrointestinal tract, Difficulty swallowing (dysphagia), Abdominal pain |
SDHB function has not been fully characterized.
Carney-Stratakis syndrome is associated with mutations in the SDHB gene on chromosome 1.
SDHC function has not been fully characterized.
Carney-Stratakis syndrome is associated with mutations in the SDHC gene on chromosome 1.
