Overview

Genomic analysis reveals unique drug-metabolizing gene variants in Amazonian Indigenous individuals, highlighting the importance of population-specific acute lymphoblastic leukemia protocols.

Key Points

To characterize pharmacogenomic diversity across drug metabolism and transport genes relevant to Berlin–Frankfurt–Münster leukemia therapy in Amazonian Indigenous populations.
Analyzed whole-exome sequencing data from 64 healthy Indigenous individuals across 12 Amazonian ethnic groups, focusing on 120 therapy-associated genes.
Annotated and filtered variants with bioinformatic quality controls, comparing allele frequencies against five 1000 Genomes Project continental populations using multidimensional scaling.
Identified 648 filtered variants, including 28 observed exclusively in the Indigenous cohort, four of which were nonsynonymous coding changes with predicted moderate impact.
Observed significant allele frequency divergence in ADA rs11555566, CBR3 rs881711, and CYP2B6 rs3745274, with rs881711 and rs3745274 differing from all five continental reference populations.
Multidimensional scaling demonstrated a distinct Indigenous pharmacogenomic profile that clustered closest to Admixed American cohorts.
