Overview
Carrier testing[1], [2], [3] - Carrier testing helps to identify carriers of the mutated genes (SMN, survival motor neuron gene). This can help to predict the risk of SMA in future pregnancies in the carriers.
- PCR-based dosage assay – Detect carriers with homozygous deletions or compound heterozygosity.
- Sequencing of the SMN gene - Detect point mutations.
- Other methods - family linkage analysis to identify the Parents genotype.
New Born screening[3] may help to identify pre-symptomatic individuals and institution of early treatment (once it becomes available). This can prevent the occurrence of severe disease forms in future.
