Advanced Testing for Mitochondrial Disease
Mitochondrial Medicine at Children’s Hospital of Philadelphia (CHOP) is emerging as the premiere center in the world for multidisciplinary clinical care, advanced diagnostics, individualized therapies, and basic, translational and clinical research dedicated to improving the health of patients of all ages living with mitochondrial disease. Integrated diagnostic tests developed at CHOP can provide definitive diagnosis, leading to better treatments.
We’ve made progress in testing and new discoveries are happening every day to create additional methods to diagnose mitochondrial disease. Our lab is CAP and CLIA certified.
Anatomic pathology testing
- Percutaneous muscle biopsy pathology testing, a novel, less-invasive sample collection through muscle biopsy that can be done in the clinic under local anesthesia
- Quantitative assays to determine percentage of mitochondrial abnormalities detected
- mtDNA genome sequencing and deletion quantification: The MitoGenome test uses long-range PCR fragment NGS next generation sequencing (NGS) analysis to target the mitochondrial genome, detecting single nucleotide variants (SNVs) with heteroplasmy (down to 1 percent) and large deletions. Heteroplasmy of large mtDNA deletions is quantified separately by ddPCR.
- Integrated exome+ mtDNA genome test
- POLG rapid sequencing
- Rapid mito DNA sequencing
- mtDNA content
- Fibroblasts and muscle respirometry
- Fibroblasts and muscle enzymology
- Blood glutathione analysis
- leukocyte CoQ10
- Blood NAD+ and NADH levels
- Brain MRS
- Rapid non-sedated brain MRI/MRS protocol
- MRI-based exercise testing
Collaboration between clinicians and researchers in Mitochondrial Medicine led by Marni Falk, MD, and Douglas C. Wallace, PhD, and genetic testing labs, led by Nancy B. Spinner, PhD, FACMG, Matthew C. Dulik, PhD, DABMG, Rebecca Ganetzky, MD, DABMG, Maria Rita-Santi, MD, PhD, Brian Harding, MA, DPhil, BM, BCh, FRCPath, and Angela Viaene, MD, PhD, has fostered CHOP’s advanced understanding of — and potential treatments for — mitochondrial disease.
If your patients would benefit from these tests, please contact us. One of our genetic counselors will reach out to you to discuss which tests are most appropriate and outline how samples should be collected, stored and sent to CHOP.
