23andme seems to be the first place to go. I have ordered from them. Hopefully they will provide me with the raw microarrays.
Then if someone discovers are particular snp linked to a disease, inorder for me to test if it is in my dna, I first I need to have the loci microarray of where it would be and then need the software search for it.
For example I would like to be able to test to see if I have a certain SNP that a researcher has linked to a disease. ( given that 23andme doesn't already test for it ).
