Dear Mrs. Jones,
The genetic profiling results show that your son carries 2 copies of the so-called “short” allele at the serotonin transporter linked polymorphic region (5-HTTLPR) and also 2 copies of the T allele of the G-703T polymorphism (rs4570625) in the tryptophan hydroxylase-2 (TPH2) gene.
Some studies find correlations between this genotype and higher amygdala activity – which, in turn – has been correlated with a number of anxiety-related traits and disorders.
In short, you may wish to expect that your son may grow up to be slightly more shy, bashful, diffident, inhibited, reticent, shrinking, hesitant, timid, apprehensive, nervous, wary, demure, coy, blushing, self-effacing, apprehensive, fearful, faint-hearted, wimpish, mousy, lily-livered, weak-kneed, unsure & doubtful.
Congratulations! He will be a handful to raise as a child but one day make a great scientist, and an even better science blogger.
