A recent study discovered an accurate way to test newborns for their genetic risk of developing type 1 diabetes.&ldquo;Previously generated <a href="https://proddocwire.wpengine.com/docwire-pick/hyperuricaemia-genetics-contribute-gou/">genetic</a> risk scores (GRSs) for type 1 diabetes (T1D) have not captured all known information at non-HLA loci or, particularly, at HLA risk loci,&rdquo; the authors wrote. Their goal, therefore, was to develop an improved GRS that took into account HLA alleles, how they interact, and non-HLA loci.<blockquote class="twitter-tweet" data-width="500" data-dnt="true">

</blockquote><script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>Researchers used the Type 1 Diabetes Genetics Consortium to compare 6,481 case patients with 9,247 controls. They called their new GRS the T1D GRS2 and compared it with previous scores. Researchers used the UK Biobank to confirm their findings.<blockquote class="twitter-tweet" data-width="500" data-dnt="true">
Honored to have been given the opportunity to work on this genetic risk score aimed at revolutionizing the way we diagnose diabetes. This will help selecting newborns at risk for type 1 diabetes to initiate preventative immunotherapies, and also help correctly diagnose adults. <a href="https://t.co/fgjZ2498X3">https://t.co/fgjZ2498X3</a>

</blockquote><script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>The new scoring method used 67 single nucleotide polymorphisms (SNPs) and evaluated 18 HLA DR-DQ haplotype variations. Researchers found their new GRS was &ldquo;highly discriminative&rdquo; in all cases of type 1 diabetes (area under the curve [AUC] 0.92; P &lt; 0.0001 vs. older scores) and performed even better for early-onset T1D (AUC 0.96). Simulated newborn screening tests found that the T1D GRS2 had almost double the efficiency of HLA genotyping on its own, performing twice as well as current genetic scores for predicting T1D in the general population.<blockquote class="twitter-tweet" data-width="500" data-dnt="true">
