Story summary

A Nature Metabolism study shows children with a family history of type 1 diabetes have risks by maternal or paternal lineage.
Children born to mothers with T1D show methylome changes that may protect against islet autoimmunity.
Researchers analyzed blood samples from 1,752 children and found DNA methylation differences linked to maternal diabetes that affect immune function genes.
A follow-up project will receive a $550,000 grant to examine these epigenetic effects.
