What was done
This narrative review synthesizes literature on human genetic variations that provide resistance to malaria. The authors describe key evolutionary adaptations, including hemoglobinopathies (sickle cell trait and thalassemia), glucose-6-phosphate dehydrogenase (G6PD) deficiency, blood group polymorphisms, and variants affecting inflammation and immune regulation.
What was found
The abstract reports no numerical findings, effect estimates, or sample sizes. It notes that the prevalence of these protective adaptations correlates with regional historical malaria burdens, while pointing out that precise biological mechanisms and gene-environment interactions remain incompletely characterized.
Why it matters
Synthesizing known genetic mechanisms of malaria resistance informs epidemiological models and may support the development of novel diagnostic, preventive, and therapeutic strategies.
Limits
The abstract provides no primary data, quantitative synthesis, or systematic search methodology. Specific protective effect sizes, allele frequencies, and detailed mechanistic pathways are omitted.
