Order Spinal Muscular Atrophy (SMA) Carrier TestSpinal muscular atrophy (SMA) is an inherited condition that affects motor neurons in the spinal cord, leading to progressive muscle weakness. Because SMA is an autosomal recessive disorder, a person can carry one altered copy of the responsible gene without developing symptoms. The Spinal Muscular Atrophy Carrier Test uses a blood sample to assess whether an individual carries a genetic change associated with SMA.
About Spinal Muscular Atrophy (SMA) Carrier Test in Colton
Carrier testing examines the SMN1 gene, which is the primary gene linked to spinal muscular atrophy.
Spinal muscular atrophy is most often caused by the loss or alteration of the survival motor neuron 1 (SMN1) gene. When both copies of SMN1 are affected, the production of a protein essential for motor neuron survival is reduced, and symptoms of SMA can appear. A carrier typically has one functioning copy and one altered copy of SMN1.
Carrier testing is commonly considered by individuals with a family history of SMA and by couples who are planning a pregnancy or are already pregnant. Because SMA follows an autosomal recessive pattern, two carriers have a chance of having an affected child with each pregnancy. Testing can help clarify reproductive risk and inform discussions with a healthcare provider or genetic counselor.
The test is performed on a blood sample and results are generally reported within one to three business days. Preparation instructions should be followed as provided by the laboratory. As with any genetic test, results are best interpreted in the context of personal and family health history, and a qualified professional can explain what a positive or negative carrier result means for an individual or couple.
