Investigating the need for routine genetic testing in pediatric cardiomyopathy patients

Genetic screening can play a vital role in improving outcomes in pediatric cardiomyopathy – a disease burdened with high morbidity and mortality rates. And though guidelines for this testing exist, uptake between practices varies.
A study led by the University at Buffalo aimed to identify the genetic mechanisms underlying the disease and investigate current clinical genetic testing practices. Their findings? Genetic testing rates varied from 0–97 percent across sites, with positive family history and hypertrophic cardiomyopathy subtype increasing the likelihood of testing (1).
21 percent of children who did not undergo genetic testing were found to have a molecular cause; both familial and idiopathic cases were among the positive results. “Even in families without a family history of cardiomyopathy, we found that many children with cardiomyopathy have a genetic cause that we can establish,” said principal investigator Steven E. Lipshultz (2), highlighting the need for routine genetic testing.
