I saw this recently on 23andMe – Consumer Genetic Testing Helps People at Risk for Hard to Diagnose Condition: https://blog.23andme.com/23andme-research/aatd-study/ Much longer article, but here are some of the relevant portions.
23andMe researchers found that direct-to-consumer DNA testing can help identify individuals who are at risk for the hard-to-diagnose genetic condition alpha-1 antitrypsin deficiency (AATD), a condition that increases the risk of lung and liver disease.
In some cases, testing not only helped flag a risk for individuals who may not have known otherwise, it also helped instigate important conversations with their healthcare provider.
Published in the journal Chest, the study is the largest to date to examine both the prevalence of AATD and the behavioral impact of learning that one carries a risk variant for the genetic condition. Another striking finding from the study was that one-quarter of those diagnosed with AATD were not diagnosed until after receiving their 23andMe Alpha-1 Antitrypsin (AAT) Deficiency Genetic Health Risk report.*
