Associated with lower IQ

The analyses demonstrated that in fetuses exposed to higher levels of BPF, methylation increases in a specific part of the GRIN2B gene, which has a key neurological role. Further, higher methylation was associated with lower IQ in the children. However, the study also found that there appears to be a sex difference in these children’s susceptibility to BPF. The epigenetic link between BPF and cognition was observed only in boys.
