In brief: It's the cause
Pernicious anemia is caused by vitamin B12 deficiency, which is most commonly caused by lack of intrinsic factor, which is a protein that's made in your stomach.
Other causes of low B12 and other vitamin deficiencies can cause a nearly identical anemia, but then they are not called "pernicious" anemia.

In brief: Vitamin B12
Pernicious anemia is caused by lack of vitamin b12.
There are a number of causes of that, but in the end, it is due to low B12 levels. The body makes large, immature red blood cells when the B12 level is low. Some people cannot absorb B12 from their stomach, so they get B12 injections, which usually solves the problem.
