Genetic analyses in a bonobo (Pan paniscus) with arrhythmogenic right ventricular cardiomyopathy.

ABSTRACT: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disorder that may lead to sudden death and can affect humans and other primates. In 2012, the alpha male bonobo of the Milwaukee County Zoo died suddenly and histologic evaluation found features of ARVC. This study sought to discover a possible genetic cause for ARVC in this individual. We sequenced our subject's DNA to search for deleterious variants in genes involved in cardiovascular disorders. Variants found were annotated according to the human genome, following currently available classification used for human diseases. Sequencing from the DNA of an unrelated unaffected bonobo was also used for prediction of pathogenicity. Twenty-four variants of uncertain clinical significance (VUSs) but no pathogenic variants were found in the proband studied. Further familial, functional, and bonobo population studies are needed to determine if any of the VUSs or a combination of the VUSs found may be associated with the clinical findings. Future genotype-phenotype establishment will be beneficial for the appropriate care of the captive zoo bonobo population world-wide as well as conservation of the bobono species in its native habitat.

Project description:Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy characterized by ventricular arrhythmias and an increased risk of sudden cardiac death. Although structural abnormalities of the right ventricle predominate, it is well recognized that left ventricular involvement is common, particularly in advanced disease, and that left-dominant forms occur. The pathological characteristic of ARVC is myocyte loss with fibrofatty replacement. Since the first detailed clinical description of the disorder in 1982, significant advances have been made in understanding this disease. Once the diagnosis of ARVC is established, the single most important clinical decision is whether a particular patient's sudden cardiac death risk is sufficient to justify placement of an implantable cardioverter-defibrillator. The importance of this decision reflects the fact that ARVC is a common cause of sudden death in young people and that sudden death may be the first manifestation of the disease. This decision is particularly important because these are often young patients who are expected to live for many years. Although an implantable cardioverter-defibrillator can save lives in individuals with this disease, it is also well recognized that implantable cardioverter-defibrillator therapy is associated with both short- and long-term complications. Decisions about the placement of an implantable cardioverter-defibrillator are based on an estimate of a patient's risk of sudden cardiac death, as well as their preferences and values. The primary purpose of this article is to provide a review of the literature that concerns risk stratification in patients with ARVC and to place this literature in the framework of the 3 authors' considerable lifetime experiences in caring for patients with ARVC. The most important parameters to consider when determining arrhythmic risk include electric instability, including the frequency of premature ventricular contractions and sustained ventricular arrhythmia; proband status; extent of structural disease; cardiac syncope; male sex; the presence of multiple mutations or a mutation in TMEM43; and the patient's willingness to restrict exercise and to eliminate participation in competitive or endurance exercise.
