Understanding Genetic Endocrine Disorders

What is a genetic endocrine disorder?

A genetic endocrine disorder is a hormonal or metabolic condition caused by a change in one or more genes.

Does a genetic disorder always run in the family?

No. Some genetic conditions are inherited from a parent, while others can occur because of a new genetic change that was not present in the parents.

Does having a genetic endocrine disorder mean my child will definitely inherit it?

Not necessarily. The risk depends on the specific genetic condition and its inheritance pattern.

When should I suspect a genetic endocrine disorder?

Genetic evaluation may be considered when there is:

• An unusually early age of disease onset
• Several affected family members
• Multiple endocrine tumours
• Unusual physical features
• Severe or unexplained obesity
• Diabetes at a young age without typical features of type 1 or type 2 diabetes
• Unusual calcium or bone disorders
• Differences in sex development
• A rare endocrine condition that does not fit the usual pattern

What is genetic testing?

Genetic testing looks for specific changes in DNA that may explain a medical condition.

Does everyone with an unusual endocrine problem need genetic testing?

No. Testing should be guided by the clinical history, examination, family history and the suspected diagnosis.
