Genes governing neurodevelopment can be modified by parental infections
Congenital neurodevelopmental disorders may be partially a result of viruses and bacteria infections.
Interference between human, viral and bacterial DNA during cell division was found to disrupt genetic regions containing genes important for early development (including in utero).
The findings were backed by 48 patient genomes. Human immunodeficiency viruses were the most often similar to essential DNA sequences.
As scientist conclude:
