|Part 3: Association Study|
You're correct. The Odds ratio is 1.36:
Odds ratio = ad/bc
Odds ratio = (7 x 48) / (31 x 8) = 1.32
95% Confidence Interval = .45 – 4.11
In this instance the confidence interval includes 1. Therefore, the allele is not a significant risk factor for AD.
PARK2 looked promising, but there might be a better candidate gene.
