Objective: To determine the single nucleotide polymorphisms (SNP) in exon 7 of the CYP2D6 gene, in ethnic inhabitants of the Community of Tempestad, Loreto. Methodology: The study was descriptive and of cross-sectional design, the population corresponded to the Quichua ethnic group, with a sample of 24 adult individuals, who previously voluntarily accepted to participate in the study, signing an informed consent; the peripheral blood sample approximately 0.8 mL was supported on filter paper. The isolated chromosomal DNA was analyzed by the QIAGEN method, which was amplified in the exon 7 region of CYP2D6, identifying the point mutations - SNP. Results: 24 DNA sequences were analyzed. of which were: 75% of the haplotypes analyzed (18/24) presented a single allelic variant within the sequence. (SNP = C/G). 4.17% of the haplotypes analyzed (1/24) presented double allelic variant within the same sequence (SNP = C/G). 20.83% of the haplotypes analyzed (5/24) did not present amplification of the product of the Polymerase Chain Reaction - PCR. Therefore, the sequence analysis could not be specified. Conclusions: It is important to highlight that the SNP (C/G) does not show interindividual genetic polymorphism in the patients studied, the nucleotide sequence of the wild type DNA, the alignment showed that there was a limited variability that refers to a risk allele, the same as refers to one or more variants located in the same copy of a gene, A risk allele is generally associated with a greater probability of developing a condition, however, by themselves they do not determine the variability of detoxification of the organism, by the simple The fact that these point mutations must first be demonstrated if they affect the amino acid sequence in the gene expression of the CYP2D6 protein.
