In case anyone is confused about this:
When you get a mutation in an exon that is listed as just "Codon XX (Y to Z)"...
And in this Codon XX there are two Ys, so you are wondering which of the two it could be...
As in "Codon 26 (G to A)" when Codon 26 is GAG...
Take a look at the beautiful genetic code and notice that it is most likely that the G in the 3rd position would result in the same amino acid, in other words, the same effect. Therefore they must be referring to the G in the first position.
If you're interested in the conversation that led me to this enlightened discovery (yes, I realize this is probably second-nature to the biologists here), it is attached below. If you use IRC be sure to check out #bioinformatics on irc.freenode.net sometime.
