Summary

Story summary

The study examined variations in monoamine oxidase A (MAOA) and serotonin transporter gene (5HTT) and their impact on serotonin levels in glioma tissue.
In male glioma patients, specific MAOA variations were linked to serotonin levels in tumor tissue.
No significant associations were observed for 5HTT variants.
Low serotonin levels in glioma tissue correlated with antidepressant use.
The study notes its observational design and the need for validation in healthy individuals.
