It is just all located at roughly the same place on one chromosome.
All evidence points to mutations on the same gene. The BEL complex is just a bunch of different alleles. Not different genes. I am unaware of any evidence to the contrary.

And if you disagree, please enlighten us to how it makes sense for it to be a bunch of different genes that are linked rather than a bunch of alleles.
