Weak D type 2.1 is similar to weak D type 2 in respect to the G385A mutation and will be mistyped as weak D type 2, if the F101I polymorphism is not checked.
The F101I substitution is conservative but expected to be in the extracellular part of RhD. A possible loss of D epitopes incurred by that mutation has not been investigated yet.
