I ran my snp data through Promethease a couple of years ago.
I've got the 4.6x risk allele for that SNP - http://www.snpedia.com/index.php/Special:FormEdit/Genotype/rs7743761(A;C)
For the ERAP1 related ones I've got 2 higher risk, 3 lower risk.
For the IL23R related ones, I've got 3 higher, 3 normal risk.
I posted some other info at the time here -
