What is 5HTT?

Answer 1

Two recent studies show that people with one or two short alleles of the 5-HTT serotonin transporter gene become depressed more often after stressful events than individuals with two long alleles of this gene.

Answer 2

5HTT, also known as the serotonin transporter protein, is responsible for the reuptake of serotonin from the synaptic cleft back into the presynaptic neuron. It plays a crucial role in regulating serotonin levels in the brain, which is important for mood regulation, emotional processing, and behavior. Changes in 5HTT function have been implicated in mood disorders such as depression and anxiety.
