## In brief

- Children whose mothers have type 1 diabetes develop the disease at about half the rate of children whose fathers have it.
- Inherited genetic risk alone does not explain this long-observed maternal effect, according to a study led by researchers at the University of Colorado.

## Why it matters

The finding shows that inherited genetic risk alone cannot account for the difference between maternal and paternal transmission of type 1 diabetes, so other factors must be considered in research on its causes.
