I don't know. That is something new. Some RSID's are skipped by 23&me probably due to not having enough coverage. Saliva is not as good DNA sample as blood. Each DNA fragment has to be read many times (typically 30 times) from different cells to reduce the errors. Perhaps if 23&me can't find enough DNA fragments to cover the same gene 30 times, it skips it.
that's make sense to me. thank you
