Invitae Small Fiber Neuropathy Test
Use
The Invitae Small Fiber Neuropathy Test analyzes up to two genes that are associated with small fiber neuropathy (SFNP), a type of peripheral neuropathy characterized by severe pain episodes that typically begin in the hands or feet, then affect larger areas of the body over time. Identification of the underlying genetic cause can help predict patient outcome and inform recurrence risk.
Special Instructions
Not provided.
Limitations
The assay achieves >99% analytical sensitivity and specificity for single nucleotide variants, insertions and deletions <15bp, and exon-level deletions and duplications. Some variants, such as structural rearrangements or complex sequences, may not be detected. It may not resolve certain variant details like mosaicism or phasing. Sequence changes in promoter and non-coding regions are not covered unless specified.
