Single Nucleotide Polymorphism (SNP) is the variation at a single position of a nucleotide chain where the DNA is formed. The association of SNPs and phenotypes is pertinent to assess the genetic basis of human health and the investigation of the genomes. The information provided by SNPs enables predicting the responses of an individual to certain drugs, as well as for the search of genes related to hereditary diseases. SNPs have been associated with complex diseases such as cardiovascular diseases, diabetes, cancer, and Alzheimer's Disease. The association between phenotypes and SNPs can be studied and evaluated using supervised Machine Learning methods. However, the literature shows that data preprocessing techniques can improve the predictive ability of the models. Since the current FAPESP project in Brazil focus on finding the relationship between Alzheimer's Disease and SNP variants using Machine Learning, the BEPE research will complement the current research, evaluating the impact of data preprocessing using statistical filters for SNPs selection. Moreover, this project plans to execute and benchmark Machine Learning models to comprehend the population structure and the accuracy in the genomic prediction. This will improve the current results already obtained and deepen the student knowledge on Data Science and Bioinformatic techniques, and on genome studies applied to the selection and treatment of SNPs.
