Hi jroc and Simply Southern,
At this point it's worth mentioning that 23andme only measure a small proportion of the quoted SNPs using SNP microarrays then use computer programs to impute (a sophisticated form of guessing) the rest. That's why the price has come down from $1000 to $150. They do state up front that their results can't reliably be used for research, for that, more exact and detailed fine mapping might be required.
I did send them an email asking which of the SNPs rs2287987, rs30187, rs10050860, rs17482078 and rs27044, was actually 'read' and which was imputed - don't know if I'll get a reply?
