Cannabis Use and Potential Epigenetic Damage to Autism Genes
Today we consider another risk factor that may be contributing to the increase in prevalence of autism and it is about the father, for a change. In the public's perception cannabis is a safe alternative way to treat all kinds of medical problems, many experts do not agree. Cannabis may Epigenetically Mark Men’s Sperm for Autism Fathers who use marijuana may be using it for two, suggests a study from Duke Medical Center. Although the study is small, encompassing just 24 men and 15 rats, it highlights a potential transgenerational effect of marijuana exposure—the passing on of sperm in which an autism-associated gene, DLGAP2, has accumulated extra epigenetic marks. The Duke scientists, led by Susan Murphy, PhD, associate professor of obstetrics and gynecology, identified significant hypomethylation at DLGAP2 in the sperm of men who used marijuana compared to controls. A similar observation was made in the sperm of rats exposed to tetrahydrocannabinol (THC) compared to controls...
