Predictions of SNP effect
The three methods we used, agree on ARG158Gln, Arg243Gln, Leu255Ser and Arg408Trp to have damaging effect and agree on Met276Val to be functionally neutral. Glu76Gly and Ser87Arg are reported to be benign by SIFT and PolyPhen and damaging, but with low reliability, by SNAP.
For the other three SNPs, there is no agreement or clear tendency of the predictions.

PolyPhen
We report here the results for PolyPhen(HumDiv) and PolyPhen(HumVar), but only consider HumVar as this is the training set recommended by PolyPhen for our task.
