With regard to biotoxin susceptibility it is reported that this haplotype is statistically correlated with an increased susceptibility to multiple biotoxins1, including but not limited to:
© Cyanobacteria derived from blue-green algae
© Venom from the northern recluse spider
© Venom from rattlesnakes
It has been suggested that the immune system of those with this haplotype may be unable or less able to properly identify and eliminate these toxins2. Multisusceptible haplotypes have been casually refered to as the 'dreaded' genes on occasion, however first hand experiences of many seem to suggest that those with this haplotype can be treated just as easily as others.
11-3-52B is additionally reported to be statistically correlated with an increased incidence of chronic fatigue syndrome. Importantly, possessing this haplotype does not mean that you have chronic fatigue syndrome. Rather it means only that you may be at an increased risk of developing chronic fatigue syndrome.
It has also been said that those with this haplotype should avoid the gardasil vaccine.
