A power analysis was conducted using Genetic Power Calculator (Purcell et al., 2003). Using a dominant test this study had 92% power to detect an association with an odds ratio of 1.3 and a minor allele frequency of 12% (α=0.05). Using recessive, genotypic and allelic tests the power to detect association was 12%, 87% and 90% respectively (α=0.05).
