Question Meaning of "D" ? ? ?

Two different FTDNA Learning Center pages specify different meanings for D in mtDNA results.

In How do I know if I have an mtDNA (mitochondrial DNA) heteroplasmy? What is the nomenclature? D stands for A or G or T heteroplasmy.

In What is a mitochondrial DNA (mtDNA) deletion? What is the nomenclature for displaying them? we read When a deletion is found in a sequence, we represent it with a D.

Anyone with D in their mtDNA results who knows?

Mr. W

I do not manage any kits with D in the results, but I have just responded to someone who is writing a program to parse mtDNA results and noticed this discrepancy.

It turned out that I do manage some kits with deletions!

However, a deletion is not D, it is d when displayed and - in the FASTA files.

So much for me trying to be smart and doing a global search for D...
