What is spinal muscular atrophy? Spinal muscular atrophy (SMA) represents a group of genetic (inherited) neuromuscular disorders that cause certain muscles to become weak and waste away (atrophy). In relation to this, spinal muscular atrophy - Wikipedia. Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting.

[3][4][5] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. Spinal Muscular Atrophy | National Institute of Neurological .... Insufficient levels of SMN protein leads to loss of motor neurons in the spinal cord and causes weakness and wasting of the skeletal muscles. The most common form of SMA is caused by the SMN1 gene; however, there are other forms of SMA associated with other genes.

Spinal Muscular Atrophy (SMA) - Johns Hopkins Medicine. Spinal muscular atrophy (SMA) is a disorder affecting the motor neurons—nerve cells that control voluntary muscle movement. These cells are located in the spinal cord. This perspective suggests that, spinal Muscular Atrophy: Causes, Symptoms, and Treatment - WebMD.

Additionally, sMA is the number one genetic cause of infant mortality. Another key aspect involves, there are four types of SMA: Type 1 is the most common and severe form of SMA. Spinal Muscular Atrophy - SMA | MedlinePlus.

Spinal muscular atrophy (SMA) attacks nerve cells in the spinal cord, weakening voluntary muscles. Read about the genetics, types, and what may help. What is Spinal Muscular Atrophy (SMA) and Causes Muscle Weakness?.

In most cases, SMA is caused by low levels of a protein called the “survival of motor neuron” (SMN) protein. The SMN protein is made with instructions from 2 regions of our DNA, called the SMN1 gene and the SMN2 gene. People usually have 2 copies of each gene, with 1 from each parent. Find out about spinal muscular atrophy (SMA) including the symptoms, types, causes, how it's diagnosed and the treatment and support available.

Spinal Muscular Atrophy (SMA) - Muscular Dystrophy Association. SMA involves the loss of nerve cells called motor neurons in the spinal cord and is classified as a motor neuron disease. From another angle, in the most common form of SMA (chromosome 5-related SMA, or SMN-related SMA), there is wide variability in age of onset, symptoms, and rate of progression.
