Ana, I've posted this several times in the past, but it's definitely worth repeating again:

For those who have downloaded their 23andMe raw data, I highly recommend viewing all articles and databases with a Firefox browser and the SNPTips add-on. This will show your personal genotype results on the page for whatever SNP location is mentioned in the article or research study (assuming it was measured by 23andme). This makes it dramatically easier to see your genetic results whenever you read something that references a SNP. For example, when Zanpar writes about the two MTHFR SNPs of interest to this thread, when I view his post, the SNPs are highlighted in green and, if 23andMe has tested for this location, it will show my personal results. No database opening, no searching, no ctrl-f, etc. Its a wonderful tool when you are reading genetic studies.
