Smoking Mom gives DNA altered fetal – Sveriges Radio

The study examined the scientists from numerous countries over 6000 mothers and their newborns. It turned out that of the newborns whose mothers had smoked daily during pregnancy, there were clear differences in the genome.

Changes synthesis in thousands of locations in the genome, including in places that were connected the genes that control the lungs and nervous system.

– we see the same epigenetic signals in neonates of smoking as we see in the genome of adult smokers, says the American researcher Stephanie London, one of the study’s authors, said in a statement.

Now scientists want , go ahead and study whether, and if so how these changes in DNA affect the development and health of children whose parents smoked during pregnancy.
