Hypothesis
Different dietary regimens and lifestyles may explain inter-population differences in NAT2 variation.
Conclusion
The study suggests that slow-causing mutations in the NAT2 gene provided a selective advantage in populations that shifted from hunting-gathering to agriculture.
Supporting Evidence
- Genetic variation at NAT2 affects the ability to metabolize various drugs.
- Positive Tajima's D values indicate an excess of intermediate frequency alleles.
- Different subsistence modes correlate with varying frequencies of NAT2 haplotypes.
Takeaway
This study looks at how different diets and lifestyles affect a gene that helps people process certain drugs, showing that some gene variations can be better for health depending on what people eat.
Methodology
The entire coding region of the NAT2 gene was resequenced in 98 subjects, and six polymorphic positions were genotyped in an additional 150 subjects.
Limitations
The study cannot rule out the existence of non-coding variants that may influence NAT2 gene expression and function.
Participant Demographics
Participants were from 12 different populations across Africa, Europe, and Asia.
