Citando:
"The authors report that among more than 1,200 people living in Italy, those with the genetic variant PDSS2 tend to drink one fewer cup of coffee per day then those without the variation.
Further analysis revealed that expression of the PDSS2 gene appears to inhibit the body's ability to break down caffeine. If that's the case, people with this variant would require less coffee to get a strong caffeine jolt because the caffeine would linger in their system for a longer time."
