- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looks back at people already reported, and it is about testing, not a new treatment.
The short version
Some families carry a gene change that raises the risk of pituitary tumors.
What was studied. Researchers reviewed all 25 patients ever published who had a large missing piece of the AIP gene. They also added three more families of their own, plus two new kinds of missing gene pieces.
What they found. People with a large missing piece looked much like people with other AIP gene changes. Their age at diagnosis, tumor size, hormone levels, and sex were about the same. Large missing pieces may show up in 8%-10% of families that carry an AIP gene change.
What this means, and what it doesn't
What it could mean: For families with pituitary tumors, the kind of gene test matters. One common test can miss these large missing pieces. Doctors may need to add a test built to find them.
What it doesn't mean: This is not a new treatment, and it is not a cure. It is a look back at cases already reported, plus a few new families. It does not change day to day care for most people. The authors also say this gene is unlikely to cause thyroid cancer.
