Invitae Comprehensive Porphyrias Panel
Use
The Invitae Comprehensive Porphyrias Panel analyzes genes associated with the porphyrias, a group of disorders caused by abnormal heme production. This test evaluates 10 genes to provide a broad panel for porphyrias, allowing for an efficient evaluation of potentially relevant genes based on a single clinical indication. The porphyrias are genetically heterogeneous, and broad panel testing is crucial for identifying the genetic cause in patients presenting with symptoms such as abdominal pain, seizures, or skin findings exacerbated by sun exposure.

Limitations
This assay uses next-generation sequencing to cover coding exons and adjacent intronic sequences but may not detect certain types of variants such as structural rearrangements or variants in promoter regions. The analysis excludes sequence changes in non-coding regions unless explicitly guaranteed. Analytical sensitivity and specificity for SNVs, insertions, and deletions <15bp are over 99%; larger events are detected with slightly reduced sensitivity. Single exon copy number events may not always be analyzed due to inherent sequence properties or data quality.
