Do we have any evidence this is due to a genetic difference? Antibodies are an immune system response, and the immune system is a learning system. Past history has a big (and complex and hard to predict) impact on how it responds to things. It could be genetic I suppose, but my guess is it would not be.

As far as i can tell, the study did not collect any patient genotype information nor does it claim antibody expression differences were do to genetic deferences between patients.
