DNA Diagnostic Testing for Familial Amyotrophic Lateral Sclerosis - SOD1 Full Gene Sequencing

  • Phone: 617-726-5721

Test DescriptionWe currenlty offer DNA mutation analysis of the superoxide dismutase 1 (SOD1) gene using PCR amplification and direct DNA sequencing of the coding exons.  More than 170 mutations have been reported in the SOD1 gene across all 5 exons. Familial amyotrophic lateral sclerosis (FALS) accounts for about 10-15% of all diagnosed ALS cases. In patients with the ALS phenotype, without a family history, we can expect on statistical grounds, therefore, to identify a SOD1 mutation in only 2-3% of "single-affected persons" studied.

Results

Results of DNA analysis will be communicated in a written report to the
referring professional.

Reason

DNA analysis is appropriate for the study of affected patients, for diagnostic confirmation in a suspected affected patient, and in prenatal testing situations after the family mutation has been identified in the proband.
