Cardiac involvement of Duchenne and Becker muscular dystrophies (DMD/BMD) is the most common cause of fatal outcomes. It is still unclear whether some DMD/BMD gene mutations might be predictive of cardiac involvement. In this study, we provide a comprehensive overview on genotypes of cardiac disease in DMD/BMD. We systematically searched the PubMed/Medline, EMBASE and Cochrane electronic databases. Search results were filtered to include only human studies, English language and all dates up to August 2019. We summarized and extensively reviewed all studies that passed the selection criteria and performed a meta-analysis on key genotype parameters of cardiac disease in DMD/BMD. Of 3450 articles scanned, we included 18 studies from 9 regions in the meta-analysis. The pooled studies included 2661 DMD/BMD patients and 1324 DMD/BMD patients with cardiac disease. The most common mutation type was exon deletion, with a pooled frequency of 90% (P

This report describes an infant presenting with deletion 22q11.2 in combination with left ventricular noncompaction and a coronary artery fistula. These two cardiac findings have rarely been reported in association with each other and have never been reported together in combination with deletion 22q11.2. The reported case demonstrates the expanding cardiac phenotype of individuals with deletion 22q11.2, suggesting that it may be appropriate to offer studies for the detection of deletion 22q11.2 to individuals with a wide range of structural cardiac defects.
