Order Spinal Muscular Atrophy (SMA) Carrier TestSpinal muscular atrophy (SMA) is an inherited neuromuscular condition caused by the loss of motor neurons in the spinal cord, which leads to progressive muscle weakness. The Spinal Muscular Atrophy (SMA) Carrier Test is a blood test used to determine whether a person carries a genetic change associated with SMA and to support prenatal diagnosis when clinically indicated.
About Spinal Muscular Atrophy (SMA) Carrier Test in Altadena
The test examines the SMN1 gene, the primary gene linked to spinal muscular atrophy, to assess carrier status.
Spinal muscular atrophy is most often caused by mutations in the survival motor neuron 1 (SMN1) gene. The condition follows an autosomal recessive pattern, meaning that a child must inherit an altered copy of the gene from each parent to be affected.
Carriers typically have one altered copy of SMN1 and one functioning copy. Carriers generally do not show symptoms of SMA, but they can pass the altered gene to their children. When both parents are carriers, each pregnancy carries a one-in-four chance of the child being affected.
The SMA Carrier Test analyzes a blood sample to detect the number of SMN1 gene copies. A reduced copy number can indicate carrier status. Because the test is used both for carrier screening and for prenatal diagnosis in appropriate situations, results should be interpreted by a qualified healthcare professional, often alongside genetic counseling.
