… The 5-HTT gene, which provides the operating code for serotonin transporters in our neuron cell walls, has a variation (or allele) which can be either long or short. The long allele is more efficient, resulting in increased gene expression and thus more serotonin transporters in the cell membrane. Inheriting the gene from both parents, each of us will have a genotype which can be long-long, short-short or a combination of the two alleles.
The study compared the subject’s genetic type with their answer to the question “How satisfied are you with your life as a whole?” – to which they could give one of five possible answers: very satisfied, satisfied, dissatisfied, very dissatisfied or neither.
The results showed that a much higher proportion of... More...
