i5039226 in 23andMe. For those lacking good common sense, like myself, this SNP is reported in the minus, meaning that 23andMe would report the deletions as insertions instead.
- That's not really correct. A deletion on the minus strand will also be a deletion on the plus strand. But the bigger problems are that (1) the numbering/position of a deletion can be tricky, especially if the deleted nucleotide is one of a string of 2 or more of that type, and, (2) 23andMe has not chosen so far to reveal publicly what exactly any "II", "DI" or "DD" in/del notation for each i-SNP on any of their chips actually represents at the nucleotide level. To put this another way, a "D" means a deletion, but on their chip, does it mean a deletion of 1 nucleotide? or 2 nucleotides? or? Same sort of problem for an "I" (insertion). 23andMe is choosing not to reveal this information to their customers, unfortunately. Greg (talk) 05:31, 30 August 2015 (UTC)
