Spinal muscular atrophy SMA is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting.

What is spinal muscular atrophy type 1. It does not usually affect life expectancy. There is no cure for SMA but there are some promising treatments being tested in clinical trials. This genetic defect is a cause of death among infants.

The disease is caused by a mutation of the survival motor neuron gene 1 SMN1. Spinal muscular atrophy 1 SMA1 also known as Werdnig Hoffmann disease is a genetic neuromuscular disorder that affects the nerve cells that control voluntary muscles motor neurons. Also known as Infantile-onset Spinal Muscular Atrophy or Werdnig-Hoffman Disease Type 1 Spinal Muscular Atrophy is caused in people who have only two copies of the SMN2 gene one present one each of the chromosome 5.

Spinal Muscular Atrophy SMA type 1 also known as Werdnig-Hoffmann disease is the most common diagnosed form of SMA accounting for approximately half of all patients with SMA. Early features of this condition are difficult and noisy breathing especially when inhaling. Spinal muscular atrophy is an inherited condition.

Spinal muscular atrophy SMA is a group of hereditary diseases that progressively destroys motor neuronsnerve cells in the brain stem and spinal cord that control essential skeletal muscle activity such as speaking walking breathing and swallowing leading to muscle weakness and atrophy. It may also appear later in life and then have a milder course of the disease. The nerve cells that service the muscles dont work properly causing muscle weakness and wasting.

Most of the nerve cells that control muscles are located in the spinal cord which accounts for the word spinal in the name of the disease. SMA hits children and adults. Children inherit the gene for SMA from both.

Spinal muscular atrophy SMA types 1 through 4 all result from a single known cause a deficiency of a protein called SMN which stands for survival of motor neuron Deficiency of SMN protein occurs when a mutation flaw is present in both copies of the SMN1 gene one on each chromosome 5. EAMS scientific opinion issued to Roche Products Limited for Risdiplam 075 mgml powder for oral solution in the treatment of type 1 and type 2 Spinal Muscular Atrophy SMA in patients 2 months. Physical therapy may also benefit patients with Type 1 SMA.

For those with Type 1 SMA treatments can include feeding tubes and ventilators and other forms of respiratory assistance. It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. Most often found in babies and small children SMA involves the nerve in the spinal cord that directs muscle movement.

Spinal muscular atrophy SMA is a genetic condition that makes the muscles weaker and causes problems with movement. This type is also called Werdnig-Hoffmann Disease. It is usually evident at birth or in the first few months afterwards 0-6 months.

Symptoms include floppy limbs and weak trunk movement. Type 1 severe SMA. Many patients with this type of spinal muscular atrophy may spend most of their lives in the hospital.

Spinal muscular atrophy SMA most often affects babies and children and makes it hard for them to use their muscles. Spinal muscle atrophy SMA is a genetic disease characterized by the progressive loss of motor neurons the nerve cells that control muscle movement. Spinal muscular atrophy with respiratory distress type 1 SMARD1 is an inherited condition that causes muscle weakness and respiratory failure typically beginning in infancy.

It is the most severe and the most common type of SMA. Spinal muscular atrophy SMA is a genetic motor neuron disease that makes it difficult to utilize the bodys muscles. And recurrent episodes of pneumonia.

Spinal muscular atrophy SMA is a genetic disease affecting the central nervous system peripheral nervous system and voluntary muscle movement skeletal muscle. Without treatment symptoms of SMA1 become apparent before 6 months of age and include worsening muscle weakness and poor muscle tone hypotonia due to loss of the lower motor neurons in the spinal cord and brain stem. A child with SMA type 1 rarely lives beyond three years of age.

The symptoms of SMA and when they first appear depend on the type of SMA you have. Its a serious condition that gets worse over time but there are treatments to help manage the symptoms.
