This SNP has been shown to be benign and play a protective role against Dystonia.
PolyPhen Score of .658 (possibly damaging); NBLOSUM100 score of 3;
p<.01 that this snp plays a protective role against dystonia in European populations
See Kamm C et al. 2008 (18519876).
The incidence of Dystonia is rare (<1%), but the incidence is decreased by this SNP
Low clinical importance, Likely protective
(The "low clinical importance, likely" qualifier is assigned automatically based on the above evidence and importance scores.)
