Expert consensus on the genetic counseling for Dystrophinopathies

Abstract

Dystrophinopathies caused by variants of DMD gene are a group of muscular diseases including Duchenne muscular dystrophy, Becker muscular dystrophy, and DMD-associated dilated cardiomyopathy. With the advancement of genetic testing techniques and wider implementation of genetic screening, especially the expanded carrier screening, more and more individuals carrying DMD gene variants have been identified, whereas the genetic counseling capacity is relatively insufficient. Currently there is still a lack of professional norms for genetic counseling on dystrophinopathies. In this consensus, the main points to be covered in the pre- and post-test consultation have been discussed, with an aim to provide genetic counseling guidance for the disease diagnosis, treatment, and family reproduction.
