DNA Diagnostic Testing for ANG Mutations Associated with Amyotrophic Lateral Sclerosis - ANG Sequencing of the Coding Region

  • Phone: 617-726-5721

Test Description

We offer direct PCR-based DNA sequencing for Angiogenin (ANG) gene mutation analysis.

Familial amyotrophic lateral sclerosis (FALS) accounts for about 10-15% of all diagnosed ALS cases. Our lab has been offering DNA test for mutations in SOD1 gene for patients with FALS. The 2006 published research studies in Irish and Scottish ALS populations as well as in US ALS populations have indicated that ANG mutations are present in more than 1% of patients with ALS. Therefore, this test is especially important for ALS patients who have tested negative for SOD1 mutations previously.

Results

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

Reason

Analysis is appropriate for the study of familial or sporadic cases where diagnostic consideration and/or confirmation in an affected individual are sought, and in prenatal testing situations after the family mutation has been identified in the proband.
