== Non-synonymous Variants ==

We tallied 1,107,05 nonsynonymous variants seen at least once across ~12,000 sequenced samples. Among the non-synonymous variants, the majority were seen only once (646,888) or twice (163,044), as expected. Of the remaining variants (297,119), a total of 260,054 were seen in at least 2 datasets and are considered as candidates for inclusion in exome SNP arrays. The transition transversion ratio of this class of variants was 2.0 in the full set of variants and 2.49 in the set of variants that were seen at least three times and in two or more studies.

The set of variants selected for array design is estimated to include 97-98% of the nonsynonymous variants detected in average genome through exome sequencing.
