Abstract
With interest, we read the article by Hastings et al1 about a 3-generation family in whom 7 members carried the titin mutation p.A178D , and 5 (3 on echocardiography and 2 on cardiac magnetic resonance imaging [MRI]) had left ventricular hypertrabeculation/noncompaction (LVHT). We have the following comments and concerns.
To date, a causal relation between mutations in any of the >40 genes and many chromosomal defects associated with LVHT and LVHT has never been proven. Arguments against a causal relation are that only a small number of patients with a certain mutation in any of these genes regarded as causative truly develop LVHT; …
期刊介绍：
Circulation: Genomic and Precision Medicine considers all types of original research articles, including studies conducted in human subjects, laboratory animals, in vitro, and in silico. Articles may include investigations of: clinical genetics as applied to the diagnosis and management of monogenic or oligogenic cardiovascular disorders; the molecular basis of complex cardiovascular disorders, including genome-wide association studies, exome and genome sequencing-based association studies, coding variant association studies, genetic linkage studies, epigenomics, transcriptomics, proteomics, metabolomics, and metagenomics; integration of electronic health record data or patient-generated data with any of the aforementioned approaches, including phenome-wide association studies, or with environmental or lifestyle factors; pharmacogenomics; regulation of gene expression; gene therapy and therapeutic genomic editing; systems biology approaches to the diagnosis and management of cardiovascular disorders; novel methods to perform any of the aforementioned studies; and novel applications of precision medicine. Above all, we seek studies with relevance to human cardiovascular biology and disease. Manuscripts are examined by the editorial staff and usually evaluated by expert reviewers assigned by the editors. Both clinical and basic articles will also be subject to statistical review, when appropriate. Provisional or final acceptance is based on originality, scientific content, and topical balance of the journal. Decisions are communicated by email, generally within six weeks. The editors will not discuss a decision about a manuscript over the phone. All rebuttals must be submitted in writing to the editorial office.
