For instance, a functionally related gene, Fanconi anemia complementation group E (FANCE), was highly differentiated across elevation in 'amakihi (Cassin‐Sackett, Callicrate, and Fleischer 2019), and FANCL and FANCI were upregulated in 'amakihi survivors reducing parasitemia and in fatalities relative to uninfected 'amakihi, respectively (Paxton et al. 2023). This evidence concerns the gene FANCI and parasitic infectious disease.
