The mutation is called CCR5-delta32 (a loss of 32 bases from the CCR5 gene).
You can search our archives for CCR5* to find previous postings on the
subject. There's been quite a bit of research done from the perspective of population
genetics, but I don't know that there's any way to obtain a commercial /
clinical test for the mutation.
