This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

Epigenome-wide meta-analysis of blood DNA methylation in newborns and children identifies numerous loci related to gestational age

In this study, researchers looked at methylation in the fetal umbilical cord blood, examining the association between methylation and gestational age.

They found that premature babies have different levels of methylation, although most of these differences do not persist into childhood. However, for 17% of these changes, they persist, potentially leading to long-term health effects. Overall 325 genes were identified as having differences in methylation.
