Help
Next-generation sequencing to identify genetic variants, including small nucleotide variants (SNVs), insertions, deletions, and copy number variants (CNVs).
For individuals with two copies of the SMN1 gene, testing for the presence or absence of the variant c.*3+80T>G will be performed to help evaluate the risk of being a silent carrier (2+0). SMN2 copy number analysis is automatically performed when 0 copies of SMN1 are detected
For premutation carriers with 55-90 CGG repeats, reflex AGG analysis will be automatically performed and reported with the Fragile X results.

Analytical Validity:
Help
Analytical sensitivity is estimated to be >99% for single nucleotide variants, >99% for insertions/deletions less than six base pairs and >98% for insertions/deletions between six and fifteen base pairs. SMN1: This test is greater than 99% sensitive for detecting the targeted mutation(s) specified. FMR1: The analytical sensitivity of this assay …
