Order Spinal Muscular Atrophy (SMA) Carrier TestThe Spinal Muscular Atrophy (SMA) Carrier Test is a blood test used to determine whether a person carries a genetic change associated with SMA. It can also be used in prenatal diagnosis when clinically indicated. Because SMA is an autosomal recessive condition, carrier status has implications for reproductive planning and family health.
About Spinal Muscular Atrophy (SMA) Carrier Test in Berkeley
Spinal muscular atrophy is a genetic disorder that affects motor neurons in the spinal cord and brainstem.
SMA is caused by changes in the SMN1 gene, which provides instructions for making a protein essential to the survival of motor neurons. When SMN1 function is reduced, motor neurons degenerate, leading to progressive muscle weakness and atrophy.
The condition follows an autosomal recessive inheritance pattern. A person who carries one altered copy of SMN1 typically does not develop SMA but can pass the altered gene to offspring. If both parents are carriers, each pregnancy carries a one-in-four chance of the child being affected.
Carrier testing examines the number and structure of SMN1 copies to identify individuals who carry a deletion or other alteration. Genetic counseling is an important companion to testing, as results can inform reproductive decisions and may prompt testing of a partner or other family members.
