Not only damaged human cells, but also healthy human cells can take up foreign DNA spontaneously. Foreign human DNA taken up by human cells will be transported into nuclei and be integrated into host genome, which will cause phenotype change. Hence, residual human fetal DNA fragments in vaccine can be one of causes of autism spectrum disorder in children through vaccination. Vaccine must be safe without any human DNA contaminations or reactivated viruses, and must be produced in ethically approved manufacturing processes.

Autism spectrum disorders have been associated with over 300 genetic mutations. As a polygenic disease, ASDs require at least one additional insult in addition to the underlying genetic susceptibility in order for manifestation of the disease phenotype (Caldwell, 2010). This work was funded by the M.J. Murdock Charitable Trust and private donations.

We were able to validate published data demonstrating the association of the degenerate 13 mer with meiotic recombination. The closer a 13 mer was to the middle of a recombination hotspot, the higher the recombination rate at that hotspot. However, binding scores for the constrained 13 mers did not demonstrate any relationship with meiotic recombination.
