Final answer:
Emery-Dreifuss Muscular Dystrophy (EDMD) is a rare genetic disorder that primarily affects skeletal muscles and cardiac muscles. It is caused by mutations in specific genes that are responsible for producing proteins involved in maintaining muscle cell structure and function. The statement 'Emery-Dreifuss Muscular Dystrophy affects skeletal or cardiac muscle' is true.
Step-by-step explanation:
Emery-Dreifuss Muscular Dystrophy (EDMD) is a rare genetic disorder that primarily affects skeletal muscles and cardiac muscles. Therefore, the statement 'Emery-Dreifuss Muscular Dystrophy affects skeletal or cardiac muscle' is True.
EDMD is caused by mutations in specific genes that are responsible for producing proteins involved in maintaining the structure and function of muscle cells. These mutations result in the weakening and degeneration of skeletal and cardiac muscles over time.
One example of a gene involved in EDMD is the EMD gene, which encodes the protein emerin. Mutations in the EMD gene can disrupt the normal interactions between emerin and other proteins in the muscle cells, leading to muscle weakness and contracture deformities.
