There are seven 23andMe SNPs covering this replacement of 3 nucleotides (TAT) with a single nucleotide (G), but the company does not reveal which if any of the following SNPs from this region actually correspond to the known cystic fibrosis mutation at this position: i5010817, i5010818, i5010819, i5006106, i5010820, i5010821 and i5010822. Our guess is that it is i5010821; if you know if this is correct, please let us know.
