Anemia anyone? Part of our Celtic heritage?

[Spartan]

Several years ago I was diagnosed with macrocytic anemia, aka pernicious anemia. The short of it is that my body no longer digests vitamin B-12 from the food that I ingest. Without B-12 the blood cells no longer carry sufficient oxygen, resulting in anemia and in the long term, permanent neurological damage. The treatment is B-12 injections and is 100% effective. I'm doing fine.

There is a hereditary factor. My brother also has low B-12 and is also receiving injections. Typically, the onset is age 40, with 60 being the average.

Doing some research, I found a statement that macrocytic (pernicious) anemia is prevalent among people with Celtic and/or Scandinavian ancestry. Prevalent, meaning that it shows up with a higher percentage among people with Celtic and Scandinavian ancestries than with people of other ethnic groups. It's still a small percentage of people, but not uncommon.

Since this forum probably has a large number of people with Celtic ancestry, (and a number of us who are in the age bracket) I am curious if there are others with this diagnosis.
