New Genetic Test May Help Identify Babies at Risk for Type 1 Diabetes

Researchers have developed a genetic screening tool that analyzes key regions of the genome to predict type 1 diabetes risk earlier than current methods. Early identification could help families watch for symptoms before serious complications develop.

A More Accurate Screening Tool

Researchers at the University of Exeter and the Pacific Northwest Research Institute in Seattle have created a new genetic screening test designed to identify babies at risk for developing type 1 diabetes. The test, called the T1DGS (Type 1 Diabetes Genetic Risk Score), analyzes specific regions of a person's genome—their genetic blueprint—to assess diabetes risk.

The test was developed after researchers studied genetic information from more than 6,500 people with type 1 diabetes, identifying genetic variations that appear linked to disease risk. This genetic foundation may help the test identify at-risk babies more accurately than current screening methods.

Why Early Identification Matters

Type 1 diabetes develops when the immune system mistakenly attacks insulin-producing beta cells in the pancreas. Importantly, this process can begin years before any symptoms appear—meaning a child could be developing the condition without anyone knowing.

If parents and doctors know a child is at risk, they can watch for early warning signs like increased thirst, frequent urination, extreme hunger, and unexplained weight loss. Catching these symptoms early may help prevent serious complications that can develop if diabetes goes undiagnosed.

What This Could Mean for Families

Early awareness of type 1 diabetes risk gives families the opportunity to be proactive. Parents can learn to recognize symptoms and seek medical attention promptly if they appear, potentially avoiding emergency situations or hospitalization.

Type 1 diabetes can develop at any age, though research shows two peak periods when diagnosis is most common. Having a genetic screening tool may help identify children during the years when they are most vulnerable to disease onset.
