Insights

Genetic testing revealed variants in ALPK3 and desmoplakin genes, highlighting the importance of genetic screening for late-onset hypertrophic cardiomyopathy. This case underscores the role of genetic factors in cardiovascular disease etiology.

Area of Science:

  • Cardiology
  • Genetics
  • Molecular Biology

Background:

  • Cardiomyopathy is a cardiovascular disease with diverse causes, including genetic mutations.
  • Genetic mutations in sarcomeric proteins are strongly correlated with cardiomyopathy presentation.
  • Late-onset hypertrophic cardiomyopathy can manifest with symptoms like chest pain and palpitations.

Observation:

  • A case report details a personal diagnosis of late-onset hypertrophic cardiomyopathy.
  • Symptoms of chest pain and palpitations were present for approximately two years.
  • The patient, a geneticist, pursued genetic testing upon diagnosis.

Findings:

  • Genetic testing identified a heterozygous variant of uncertain significance (VUS) in the ALPK3 gene (c.399dup).
  • A heterozygous VUS was also found in the desmoplakin (DSP) gene (c.7552G>A).
  • These genetic findings are associated with the patient's hypertrophic cardiomyopathy.

Implications:

  • This case emphasizes the critical role of genetic screening in identifying the etiology of cardiomyopathy.
  • Understanding genetic variants in genes like ALPK3 and DSP is crucial for diagnosing and managing cardiovascular diseases.
  • Autobiographical case reports can illuminate the clinical significance of genetic testing in personalized medicine.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
