Invitae Myotonia and Paramyotonia Congenita Panel
Use
The Invitae Myotonia and Paramyotonia Congenita panel analyzes 2 genes associated with non-dystrophic forms of myotonia. This panel is useful for individuals with clinical signs and symptoms of myotonic syndromes to confirm the diagnosis, provide anticipatory guidance, help determine which relatives are at risk, and guide enrollment in clinical trials. It is especially helpful when the inheritance pattern or disease presentation is unclear, given the multiple inheritance patterns and variable phenotypes of these conditions.
Special Instructions
Not provided.
Limitations
The assay achieves >99% analytical sensitivity and specificity for SNVs, indels 15bp but smaller than a full exon may be slightly reduced. Single-exon copy number events may not be analyzed due to sequence properties or data quality. Structural rearrangements and variants in complex sequences may not be detected. Variants outside the covered regions, such as non-coding regions, are not analyzed unless coverage is explicitly stated.
