Study finds key genetic differences between male and female placentas
DNA
National Institutes of Health May 1 2025 The genes of male and female placentas have marked differences in how they are expressed, according to a study by researchers at the National Institutes of Health (NIH) and other institutions. These differences involve the presence or absence of tags on DNA known as methyl groups, which switch genes on or off without changing their structure. Understanding these DNA methylation patterns may inform future research on the higher risk for pregnancy
