Spinal Muscular Atrophy Type 2
Spinal Muscular Atrophy Type 2 (SMA Type 2) is a genetic disorder that affects the motor neurons in the spinal cord, leading to muscle weakness and atrophy. It is caused by a deficiency of the survival motor neuron (SMN) protein, which is essential for the health of motor neurons. Symptoms typically appear between 6 and 18 months of age, and affected individuals may have difficulty sitting, standing, or walking independently.
Children with SMA Type 2 often have a normal lifespan but may require supportive therapies, such as physical therapy and assistive devices, to improve mobility and quality of life. Early diagnosis and intervention can significantly enhance outcomes for those affected by this condition.
