Order Spinal Muscular Atrophy (SMA) Carrier TestSpinal muscular atrophy (SMA) is an inherited neuromuscular disorder marked by the loss of motor neurons in the spinal cord, which leads to progressive muscle weakness and atrophy. The Spinal Muscular Atrophy (SMA) Carrier Test is a blood test used to determine whether an individual carries a genetic change associated with SMA and, in certain contexts, to support prenatal diagnosis.
About Spinal Muscular Atrophy (SMA) Carrier Test in Bethlehem
The test examines the SMN1 gene, the primary gene linked to spinal muscular atrophy.
Spinal muscular atrophy is most often caused by the loss or alteration of both copies of the SMN1 gene. A person who carries one altered copy is considered a carrier and typically does not develop symptoms, but carriers can pass the altered gene to their children.
The Spinal Muscular Atrophy (SMA) Carrier Test analyzes a blood sample to detect the number of functional SMN1 gene copies. A reduced copy number indicates carrier status. Because SMA is an autosomal recessive condition, two carriers have a chance of having an affected child with each pregnancy.
This test is used for carrier screening and can also aid prenatal diagnosis when clinically indicated. Results are interpreted by a healthcare provider in the context of family history and other genetic findings.
