SMA has autosomal recessive inheritance, i.e., if two SMA carriers have a child, there is a 1 in 4 (25%) chance that the child will have SMA.

However, genetic counseling is crucial so that parents can make informed decisions about having children. Some carriers have two SMN1 copies on the same allele. 0000001867 00000 n Typical symptoms include: • A diagnosis of SMA is confirmed if a patient with muscle weakness has zero copies of SMN1. (1+1 or 1+2) of the SMN1 gene. 0000008852 00000 n Both affect children, but the age of onset and severity are more variable.

Copy number testing cannot detect these small changes. 0000002253 00000 n Both the American College of Obstetricians and Gynecologists and the American College of Medical Genetics and Genomics recommend SMA carrier screening for those who are considering pregnancy, or for those who are pregnant and have not been previously tested. • In a person with muscle weakness, having 2 SMN1 copies means it is unlikely that SMA is the cause of their symptoms.

Prenatal testing is available. Page last reviewed: 4 May 2020 • People with 2 or more copies of the SMN1 gene are unlikely to be SMA carriers, but there is still a small (less than 1%) residual risk. Spinal muscular atrophy (SMA) is a genetic disorder that affects the nerves of the spine. In March 2017, the American College of Obstetricians and Gynecologists (ACOG) updated their genetic carrier screening recommendations to include screening for spinal muscular atrophy.

If you are considering pregnancy, or are pregnant and have not been previously tested, talk to your healthcare provider about carrier screening. Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease that damages the nerve cells that interact with muscles. getting pregnant and waiting to see if your child is born with SMA, or having tests during pregnancy to see if they will have it using donated sperm or eggs to get pregnant pre-implantation genetic diagnosis (PGD) – where a woman's eggs are fertilised in a laboratory and the resulting embryos are tested for SMA before being put in the womb For example: The charity Spinal Muscular Atrophy UK provides more information and advice if your child has recently been diagnosed with SMA.

The estimated incidence of SMA is 1 in 6,000 to 1 in 10,000 live births, and a carrier frequency of 1/40 – 1/60. • If a symptomatic person has 1 SMN1 copy, their doctor may consider sequencing the SMN1 gene to determine if they have a small change in the copy that prevents it from working properly.

Our Spinal Muscular Atrophy Testing Technical Brief provides a summary of the key elements of this test, including clinical significance and indications, interpretation of results, methodology, and specimen requirements. • In healthy people, having only 1 copy of SMN1 means the person is a SMA carrier. 0000056651 00000 n

The SMN1 gene, if mutated, can cause SMA. In most cases, SMA carriers have only one copy of the SMN1 gene, while the second copy is deleted (1+0). Spinal muscular atrophy is a genetic disease that results in progressive muscle weakness and paralysis.
