Additional genotypes used in modeling studies derived included 1) EURNIHLN genotypes (254 subjects) that were available from the NIH Laboratory of Neurogenetics at the Coriell Queue website, 2) East Asian genotypes from the iControlDB (198 subjects), 3) East Asian samples (85) genotyped at North Shore and 4) African American genotypes (1847 subjects) from the iControlDB. For the modeling studies we limited the genotypes to autosomal SNPs that were typed in >95% of each of the included subjects and that were in HWE (p>0.001) within a given self-identified group and in combined samples from a given continent.
