Order Spinal Muscular Atrophy (SMA) Carrier TestSpinal muscular atrophy (SMA) is an inherited condition that affects motor neurons in the spinal cord and brainstem, leading to progressive muscle weakness. The SMA carrier test is a blood test designed to determine whether a person carries a genetic alteration associated with the condition.
About Spinal Muscular Atrophy (SMA) Carrier Test in Plum
Carrier testing examines the SMN1 gene, which is the primary gene linked to spinal muscular atrophy.
Spinal muscular atrophy is an autosomal recessive disorder, meaning that a child must inherit an altered copy of the SMN1 gene from each parent to be affected. Carriers typically have one altered copy and one normal copy of the gene, and they usually do not show symptoms of the condition.
The SMA carrier test analyzes the SMN1 gene to identify deletions or other changes that reduce its function. Because the SMN1 gene has a nearly identical neighboring gene called SMN2, laboratory methods must be precise enough to distinguish between the two when counting gene copies.
Results are generally reported as carrier or not a carrier based on the number of functional SMN1 copies detected. In some cases, a result may be inconclusive, and genetic counseling can help interpret what the findings mean for family planning and health decisions.
