Maffucci Syndrome Panel | NGS
| Genes Sequenced | 2 genes sequenced: IDH1 and IDH2. |
| Test Details | This targeted hybrid capture-based test is designed to detect somatic single nucleotide variants, insertions and deletions (indels). At a mean depth of coverage of at least 4000x across the captured region, this test has 89.84% sensitivity for variants at a variant allelic fraction (VAF) of 1.25% and 99.48% for variants at a VAF of at least 2.5%. Identified variants classified using ACMG/AMP, ClinGen and internally developed guidelines. |
| Methodology | Next Generation Sequencing |
| Performed | Monday – Friday |
| Turnaround | 3 weeks |
| Specimen Requirements | Fresh or Formalin fixed paraffin embedded tissue from the affected area. |
| Sample Collection | Fresh tissue placed in media (4 mm skin punch or tissue 4 mm in size). Routine Tissue Block: One (1) formalin fixed paraffin embedded (FFPE) block or 15 unstained slides with matched H&E slide. |
| Minimum Sample Volume | 3 millimeters |
| Storage/Transport Conditions | Fresh tissue: Refrigerated temperature (cold packs). Please ship in media for overnight delivery. FFPE blocks: ambient /room temperature. Place in a sealed container (bag). Place primary container in a padded envelope for overnight delivery. In seasonal warmer weather, include cold pack. |
| Unacceptable Conditions | FFPE specimens processed using acid decalcification are not acceptable (EDTA is acceptable) |
