Is Empty Sella Syndrome hereditary?

Empty Sella Syndrome is generally not considered a hereditary or strictly genetic condition, but rather a structural finding where the pituitary gland appears flattened or absent on imaging. While most cases occur sporadically, it is rarely associated with underlying genetic connective tissue disorders, meaning it is not typically passed down through families in a predictable Mendelian pattern.

Is Empty Sella Syndrome hereditary?

In the vast majority of cases, Empty Sella Syndrome is not hereditary. It is classified as either primary, where the cause is often related to increased intracranial pressure or anatomical variations in the diaphragma sellae, or secondary, resulting from pituitary injury, surgery, or radiation. Because Empty Sella Syndrome is typically an acquired structural anatomical feature, it does not follow autosomal dominant, recessive, or X-linked inheritance patterns.

When is genetic testing recommended for Empty Sella Syndrome?

Genetic testing is not standard for patients diagnosed with Empty Sella Syndrome. However, clinicians may consider genetic evaluation if the condition is discovered alongside symptoms of a connective tissue disorder, such as Ehlers-Danlos syndrome or Marfan syndrome. In these rare instances, the Empty Sella Syndrome is considered a secondary feature of a broader genetic syndrome rather than a primary diagnosis.

What are the risk factors for family members?

Because Empty Sella Syndrome is generally not an inherited disorder, there is no calculated risk percentage for children of an affected parent to develop the condition. Unlike single-gene disorders, there are no known de novo mutations that directly cause Empty Sella Syndrome in isolation. The risk to siblings or offspring of an individual with Empty Sella Syndrome is considered to be the same as that of the general population.

• Primary Empty Sella Syndrome: Often linked to obesity, hypertension, or pregnancy.


• Secondary Empty Sella Syndrome: Often linked to prior surgery, trauma, or pituitary tumors.


• Clinical Evaluation: Focuses on endocrine function (hormone levels) rather than genetic markers.

Next steps

• Consult an endocrinologist to monitor pituitary hormone function.


• Share your experience with the 15 members of our Empty Sella Syndrome community on DiseaseMaps.org.


• Discuss any family history of connective tissue disorders with a primary care physician to determine if a referral to a geneticist is warranted.
