Genetic cardiomyopathies encompass various types, with hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), and arrhythmogenic right ventricular cardiomyopathy (ARVC) being among the most common. Each type is characterized by specific genetic mutations and clinical features, making precise diagnosis and targeted treatment essential.

• B. Inheritance Patterns

Understanding how genetic cardiomyopathies are inherited is fundamental in assessing family risk and guiding screening efforts.

1. Autosomal Dominant

Autosomal dominant inheritance means that a single copy of the mutated gene from one parent is sufficient to cause the condition. Consequently, offspring of affected individuals have a 50% chance of inheriting the mutation, highlighting the importance of early detection and intervention in families with a history of genetic cardiomyopathies.

2. Autosomal Recessive

Autosomal recessive inheritance necessitates the inheritance of two mutated genes, one from each parent, to manifest the condition. Often, parents are carriers without exhibiting any symptoms themselves. Identifying carriers within a family is crucial for assessing the risk of future generations.

3. X-linked

X-linked inheritance involves genes located on the X chromosome. Males are more commonly affected due to having only one X chromosome, while females can be carriers. This unique inheritance pattern emphasizes the importance of genetic counseling and screening to identify carriers and at-risk individuals within families.

• C. Risk Factors

Identifying risk factors associated with genetic cardiomyopathies is pivotal in targeting at-risk families and individuals effectively.
