So easy-peasy that I haven't got a clue!!!!!!!!

I presume that it has something to do with Ch/Rg as the HLA genes are on Chromosome 6, but that is all I can say?

:confused::confused:

By the way, CROZ was so-called because the propositus came from Australia!

:haha::haha:

you're on the right track! this particular haplotype cannot align correctly with comparable haplotypes because it is shortened due to a deletion of a segment of the Class III MHC cluster which removes the C4A gene which carries the Rodgers antigen determinant so it would be unexpected for Rodgers antigen to be expressed from this haplotype

^^Well if Malcolm hasn't a clue, then I don't stand a chance! LOL. I'll have to research this one when I have more time and not at the end of my work shift--time to go home now!
