<div class="spaceAbove">While most people with familial hypertrophic cardiomyopathy are symptom-free or have only mild symptoms, this condition can have serious consequences. It can cause abnormal heart rhythms (arrhythmias) that may be life threatening. People with familial hypertrophic cardiomyopathy have an increased risk of sudden death, even if they have no other symptoms of the condition. A small number of affected individuals develop potentially fatal heart failure, which may require heart transplantation.\n\nThe symptoms of familial hypertrophic cardiomyopathy are variable, even within the same family. Many affected individuals have no symptoms. Other people with familial hypertrophic cardiomyopathy may experience chest pain; shortness of breath, especially with physical exertion; a sensation of fluttering or pounding in the chest (palpitations); lightheadedness; dizziness; and fainting.\n\nNonfamilial hypertrophic cardiomyopathy tends to be milder. This form typically begins later in life than familial hypertrophic cardiomyopathy, and affected individuals have a lower risk of serious cardiac events and sudden death than people with the familial form.\n\nIn familial hypertrophic cardiomyopathy, cardiac thickening usually occurs in the interventricular septum, which is the muscular wall that separates the lower left chamber of the heart (the left ventricle) from the lower right chamber (the right ventricle). In some people, thickening of the interventricular septum impedes the flow of oxygen-rich blood from the heart, which may lead to an abnormal heart sound during a heartbeat (heart murmur) and other signs and symptoms of the condition. Other affected individuals do not have physical obstruction of blood flow, but the pumping of blood is less efficient, which can also lead to symptoms of the condition. Familial hypertrophic cardiomyopathy often begins in adolescence or young adulthood, although it can develop at any time throughout life.\n\nHypertrophic cardiomyopathy is a heart condition characterized by thickening (hypertrophy) of the heart (cardiac) muscle. When multiple members of a family have the condition, it is known as familial hypertrophic cardiomyopathy. Hypertrophic cardiomyopathy also occurs in people with no family history; these cases are considered nonfamilial hypertrophic cardiomyopathy. </div>

<div class="spaceAbove">Arrhythmogenic right ventricular cardiomyopathy/dysplasia-13 (ARVD13) is characterized by progressive fibrofatty myocardial replacement, primarily of the right ventricle. The main clinical features are structural and functional abnormalities of the ventricles, electrocardiographic depolarization/repolarization changes, reentrant arrhythmias, and sudden death (summary by van Hengel et al., 2013).</div>

<div class="spaceAbove">Familial cardiomyopathy caused by mutation in the FLNC gene has been described as hypertrophic, restrictive, dilated, or arrhythmogenic right ventricular cardiomyopathy. Affected individuals, especially those with dilated cardiomyopathy, are at risk for arrhythmias and sudden death. Arrhythmias without cardiomyopathy, and left ventricular noncompaction, have also been reported (Ortiz-Genga et al., 2016; Verdonschot et al., 2020).</div>

<div class="spaceAbove">Arrhythmogenic right ventricular cardiomyopathy/dysplasia-14 (ARVD14) is characterized by palpitations, chest pain, and presyncope. Electrocardiography shows epsilon waves, T-wave inversion across anterior leads, premature ventricular contractions, ventricular tachycardia, and left bundle branch block. Dilation of the right ventricle with hypokinesia and aneurysmal changes are seen on echocardiography. Cardiac MRI may show fibrofatty infiltration, which has been confirmed by endocardial biopsy in some patients. Sudden death may occur (Mayosi et al., 2017).&#13; For a discussion of genetic heterogeneity of ARVD, see ARVD1 (107970).</div>
