Here the candidate genes for A- trait are studied and show that it correlates with better reaction to stress, regulating more quickly after an injury.

And a gene possibly related to traits N or A as a modifying gene (MAOA) shows poorest adaptation to an injury.

The candidate gene for P trait (not shown in the 1000 genome link I posted above) shows the opposite reaction, holding on to an injury as opposed to adapting to it.
