Prediction of nsSNPs was conducted on three representative proteins for Alzheimer's, Parkinson’s, and Huntington’s diseases; APPl in Drosophila melanogaster, LRRK1 in Aedes aegypti, and VCPl in Tribolium castaneum. With the possibility of using insect models to investigate neurodegenerative diseases. Here, APPL1 is linked to neurodegenerative disease.
