<i>CRH-BP</i> genotypes in Plains Indians: association with resting EEG alpha power and anxiety disorders.

The table shows mean (S.D.) alpha power for individuals with each genotype (11, 12, 22). P values are derived from ANOVA; alpha power variation between genotypes (2 df) and between homozygotes (1df). Alpha power: log10 of absolute spectral power (µv2) in 8–13 Hz frequency band. Alpha power was maximal at PZ (central parietal electrode). The table shows the frequency of allele 1 in individuals with lifetime DSM-III-R anxiety disorders (anx) (N = 41) and no anxiety disorders (Non-Anx) (N = 282). P values are derived from a χ2 analysis across genotypes (2 df) and across alleles (1 df). MAF = minor allele frequency. Rs6453267 is monomorphic in this population.
