I hear that the recent L459 test results may have mistakenly been listed as L21+, when in fact, they were L21-.
I hope not too many people have been misled & ordered tests on the strength of those results!
Can you be more specific? Is there some new instance?
We have the case a couple of months ago where an L459- result was found (for the first time ever) in an L21+ person but it turns out the L21 result was in error and it and he was really U152+. I don't see how any of this would caused a wasted result.
Everyone who is L21** (L21+ DF13- DF63-) and everyone who is P312* (P312+ L21- U152- DF27-) should consider L459 testing. We don't know if it is above or below L21. We know L459 is below P312, but parallel to U152 and DF27.
