Types of Spinal Muscle Atrophy
SMA or spinal muscular atrophy is an inherited condition, which affects only one in 6000-10,000 people. When someone suffers from SMA, they lose control over their muscle movements. Usually, people with SMA undergo a gene mutation. The symptoms, onset, as well as, the progression of SMA vary from one person to another. Here, we’ll discuss with you some rare types of spinal muscle atrophy. Rare types of SMA The rare types of spinal muscle atrophy are usually caused as a result of gene mutation. Typically, there are three rare types of SMA. These include: SMARD Spinal muscular atrophy with respiratory distress is a rare type of SMA and is primarily caused by the mutation of the IGHMBP2 gene. This SMA is predominantly diagnosed in infants and leads to severe breathing problems in them. Some of the early warning signs of SMARD include noisy and difficult breathing, pneumonia that relapses frequently, inability to take the feed, and a feeble cry. Infants between the age of six weeks to six months will undergo a sudden incapacity to breathe because of paralysis of the muscles, which separate the diaphragm and the abdomen. SMARD is inherited in what is called the autosomal recessive pattern.
