Long QT affects more people than estimated
THE prevalence of the genetic arrhythmogenic disorder, long QT syndrome (LQTS), may be significantly higher than previously thought. Italian researchers who conducted the first large-scale population-based study of its prevalence say it may be present in as many as one in every 2500 people, far more than previous estimates. They conducted ECG-guided molecular screens in 44,596 infants aged 15-25 days old. In total, 17 of 43,000 white infants were affected by LQTS. Approximately 515 family members of genotype-positive infants were found to carry disease-causing mutations. “ECG-guided molecular screening can identify most infants affected by LQTS ...
Genetic screening should be routine in sudden death post-mortems: experts
POST-mortems following sudden unexplained death should include routine screening for genetic mutations such as long QT syndrome to improve diagnosis and prevention of sudden death among first-degree relatives, experts say. Professor Chris Semsarian, a molecular cardiologist at the Royal Prince Alfred Hospital and the Centenary Institute in Sydney, told the Cardiac Society of Australia and New Zealand Annual Scientific Meeting in Sydney last weekend that post-mortem DNA testing was especially warranted in deaths under the age of 35. Professor Semsarian said genetic screening of family survivors identified an average of 8.9 family members at risk of sudden death ...
