Hi Ralph,
I think that is a fine question which hopefully has a finite answer though surely in the infinite universe I am lost without finding it. Finis.
Moving past my punny response, I don't recall if the numerous documents I received (and have long since recycled with client's hearty approval) indicated if other materials matter for sensitivity and genetic links. I wouldn't be surprised to learn of either being the case.
The case was beryllium alloys with nickel and copper and none of several opposing counsels attempted to differentiate the alloys in question from the literature.
At AIHce 2016 (or so) there was a roundtable on beryllium where the tox and epi data on sensitivities was presented. A "well" known provider of beryllium participated in the RT.
I hope this helps.
Be well, ;-)

> >Doctors, toxicologists, and other beryllium professionals all testified. The literature and cases are fascinating in how little beryllium it takes. Beryllium is a sensitizer and there is a genetic component to this sensitivity.

Does this toxicity depend on what compound the Beryllium is associated with?
