cardiomyopathy, familial hypertrophic, 28

Cardiomyopathy, familial hypertrophic, 28 is a form of heart muscle disease that primarily affects the structure and function of the heart. This condition is associated with genetic changes in FHOD3 and is inherited in an autosomal dominant pattern. It most commonly presents with abnormal thickening of the heart muscle, particularly in the ventricular septum, which can affect blood flow and heart rhythm. Precise prevalence estimates are not well established, and not all individuals with the genetic variant experience the same set or severity of cardiac symptoms.

The clinical presentation of cardiomyopathy, familial hypertrophic, 28 is primarily characterized by structural and functional abnormalities of the heart. A large proportion of affected individuals demonstrate asymmetric septal hypertrophy, which is a marked thickening of the wall separating the heart’s chambers. Other features that may be observed include left atrial enlargement and myocardial late gadolinium enhancement, as seen on cardiac imaging studies. Some patients also experience systolic anterior motion of the mitral valve, atrial fibrillation, and signs of left ventricular outflow tract obstruction. In addition, a subset of individuals may develop complications such as stroke, sudden cardiac death, or reduced left ventricular ejection fraction. Not all individuals experience all features, and severity varies considerably.

Cardiomyopathy, familial hypertrophic, 28 is linked to genetic variants in the FHOD3 gene. FHOD3 plays an important role in the regulation of the cardiac muscle cytoskeleton, and disruptions in its function can lead to abnormal heart muscle structure and function. The condition is inherited in an autosomal dominant pattern, which means that a single copy of the altered gene can contribute to the development of the disease. As a result, each child of an affected individual has a 50% chance of inheriting the genetic variant. That not every individual who inherits the variant will necessarily develop the full spectrum of symptoms, reflecting variable expressivity.

Currently, management of cardiomyopathy, familial hypertrophic, 28 focuses on supportive care and symptom management. Treatment is tailored to the individual and often involves a multidisciplinary team to address issues such as cardiac rhythm abnormalities and structural heart changes. In the absence of therapies specifically approved for this condition, patients benefit from regular monitoring and interventions aimed at managing symptoms and preventing complications. Genetic counseling is recommended to help families understand the inheritance pattern and discuss appropriate management and family planning options. Patients should discuss treatment options with their healthcare team to determine which therapeutic strategies may be most appropriate for their specific situation.

The course of cardiomyopathy, familial hypertrophic, 28 can vary widely among affected individuals. With current standards of care, many patients live into adulthood, though some may face complications such as arrhythmias or reduced heart function over time. Outcomes described in medical literature continue to evolve as standards of care improve, and factors such as age at diagnosis and access to specialized care play significant roles in determining long-term health. Families often find it helpful to connect with cardiology specialists and genetic counselors, who can provide guidance tailored to the unique aspects of each case.

A clinical trial is currently underway exploring new treatment approaches for cardiomyopathy, familial hypertrophic, 28. Individuals interested in learning more about clinical trials can search ClinicalTrials.gov or consult their care team about potential eligibility for emerging therapies.
