Order Spinal Muscular Atrophy (SMA) Carrier TestThe SMA Carrier Test is a blood-based genetic test that assesses whether a person carries a mutation associated with spinal muscular atrophy. Because SMA is an autosomal recessive condition, carriers typically have no symptoms but can pass the altered gene to their children. This test is used both to determine carrier status and, in certain clinical settings, to support prenatal diagnosis.
About Spinal Muscular Atrophy (SMA) Carrier Test in Alton
Spinal muscular atrophy (SMA) is a genetic disorder that affects motor neurons in the spinal cord, leading to progressive muscle weakness and atrophy.
SMA is inherited in an autosomal recessive pattern, which means that a person must inherit two altered copies of the responsible gene—one from each parent—to develop the condition. Individuals who carry only one altered copy are known as carriers and generally do not show symptoms.
Most cases of SMA are caused by mutations in the SMN1 gene. The severity of the condition can vary, and the number of copies of a related gene, SMN2, can influence how the disease presents. Carrier testing focuses on detecting the presence of a changed SMN1 gene.
The SMA Carrier Test analyzes a blood sample to identify carriers of the most common SMA-causing mutations. Results are typically available within 1-3 business days. Preparation instructions should be followed as provided by the laboratory performing the test.
