Detailed explanation-1: -Who is more likely to get spinal muscular atrophy? The most common form of SMA is caused by a mutated or missing gene known as the survival motor neuron gene 1 (SMN1).
Detailed explanation-2: -Spinal muscular atrophy (SMA) is an autosomal recessive disorder that is the leading genetic cause of infantile death. SMA is characterized by loss of motor neurons in the ventral horn of the spinal cord, leading to weakness and muscle atrophy.
Detailed explanation-3: -Spinal muscular atrophy (SMA) is an inherited (genetic) condition that affects the nerves leading to the muscles, known as motor nerves. SMA prevents the muscles from receiving messages from the brain. Over time, the muscles become weaker and waste away. This process is known as atrophy.
