[Specification for genetic diagnosis of congenital heart disease].

Congenital heart disease (CHD) is one of the most common congenital malformations and a major cause of mortality among neonates and children. Conventional methods for the diagnosis of CHD have relied on clinical features and imaging findings. With the rapid development of genetic techniques, to identify the cause of CHD through genetic diagnosis has gained great significance for the early diagnosis, treatment, and prevention of CHD. However, currently there is still a lack of norms and standards for the genetic diagnosis of CHD. In view of this, experts from the relevant fields have formulated the present norm by integrating the latest research advances on CHD-related genes with the current clinical practice on the diagnosis and treatment of CHD and status quo of genetic diagnosis in China. The norm has been recommended by the Cardiology Section of the Chinese Medical Education Association, the Medical Genetics Branch and the Heart Group of Pediatric Surgery Branch of the Chinese Medical Association, which has formulated the procedures and norms of genetic testing, prenatal diagnosis, and genetic counseling for CHD, with an aim to provide reference for clinicians as the standards for the integrated diagnosis, early treatment, and prevention of CHD.
