Honestly it would be near impossible to do this with (im guessing your somewhat limited recourses and education) but if you want a chance of identifying something I would look at GWAS (genome wide association studies) almost all of the data that they collect is available to the public. Basically what you can do is match some measured phenotypes to realtive frequencies of different alleles. This is sort of a bioinformatics thing but there is just a swamp of data that has not been sorted through so finding something kind of new in there would probably be your best bet. However you would probably need to do a bit of research into what GWAS studies are how they work and how you can contribute. Heres an introduction to GWAS its probably mind-numbingly boring but not sure what your working with. https://www.coursera.org/learn/disease-genes/lecture/iFQ1J/introduction-to-genome-wide-association-studies-historical-overview
