Evaluating amateur bioinformatics results
You need to understand the biological significance of the 33-mer locus. 


I'd blast your 33-mer on NCBI and see what the biological significane is of the locus. If might be a transposon/ promoter region. 
Look at the translation of the protein and if its part of a protein the location within the protein structure.   
Blast the entire locus including 5' and 3' regions of the 33-mer target
Carefully assess the results for chance, e.g. conserved protein and the synonymous mutations just happened to drop out (Poison distribution).


Once you gain a greater understanding, it is likely to have been identified before and what you might contribute is a different method to obtain a known result.

In summary, you need the next level part of the course about translating a genetic correlation into a biological result/ mechanism. This isn't research grade work at present in my opinion.
