AKT1 Gene Overview
What it Does:
The AKT1 gene produces a protein called AKT1 kinase, which plays a vital role in cell growth, survival, and communication. In the brain, AKT1 signaling supports nerve cell function, memory formation, and communication between brain cells. It is also involved in responding to the release of dopamine, a chemical messenger that affects mood, behavior, and cognition.
Why This Matters to You:
Variations in the AKT1 gene can influence how your brain processes dopamine, especially in response to substances like cannabis. These differences may affect your risk of developing psychotic symptoms.
Understanding the AKT1 Variant
Key Mutation:
- G1172+23A (T>C)
This variant impacts how dopamine is processed in the brain, particularly when influenced by THC, the active compound in cannabis.
Impact of the C Allele
Impact Allele:
- C Allele (Negative)
What It Means for You:
Carrying the C allele is linked to:
- Dopamine Processing:
- Reduced responsiveness to dopamine, leading to dopamine remaining active in the brain for longer periods.
- Cannabis Use and Psychosis Risk:
- When cannabis is used, THC stimulates dopamine release. In C allele carriers, this prolonged dopamine activity is associated with an increased risk of psychotic symptoms.
- Studies have shown that:
- C allele carriers who use cannabis daily are at a significantly higher risk of developing psychosis.
- CC carriers have a seven-fold increase in the odds of psychosis compared to TT carriers.
What This Means for You
- If you carry the C allele:
- Be cautious with cannabis use, as it can increase your risk of psychotic symptoms. Avoiding or limiting cannabis consumption may help reduce this risk.
- Consider discussing your genetic profile with a mental health professional if you are concerned about your susceptibility to psychosis or other dopamine-related conditions.
Next Step:
Speak with a genomics specialist or doctor to better understand how your AKT1 gene affects your brain’s dopamine response and what steps you can take to protect your mental health.
