Pricing Comments

We are happy to accommodate requests for testing single genes in this panel or a subset of these genes. The price will remain the list price. If desired, free reflex testing to remaining genes on panel is available. Alternatively, a single gene or subset of genes can also be ordered via our Custom Panel tool.

An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.

Click here for costs to reflex to whole PGxome (if original test is on PGxome Sequencing platform).

Click here for costs to reflex to whole PGnome (if original test is on PGnome Sequencing platform).

Turnaround Time

3 weeks on average for standard orders or 2 weeks on average for STAT orders.

Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics

Clinical Features

Medulloblastoma is a primary central nervous system (CNS) malignant tumor that is more commonly observed in the pediatric population, as it affects approximately 9.6 children and 0.54 adults per million individuals (Smoll and Drummond. 2012. PubMed ID: 22981874). It is also more commonly reported in males than females (Khanna et al. 2017. PubMed ID: 28828582). The tumor starts in the brain at the base of the skull in the posterior fossa, and tends to spread to other areas of the brain and spinal cord. Individuals with medulloblastoma may experience issues with walking, balance, fine motor skills, headaches, nausea, seizures and other features. Treatment usually consists of surgery to remove as much tumor as possible and subsequent treatment by radiation and/or chemotherapy leading to improved prognosis and increased surveillance (Kameda-Smith. 2020. PubMed ID: 32095940).


Most cases of medulloblastoma are thought to be sporadic and have been stratified into molecular subgroups depending on the underlying biology and patient clinical characteristics (Juraschka and Taylor. 2019. PubMed ID: 31574483). These subgroups include wingless [WNT], sonic hedgehog [SHH], group 3, and group 4. However, there are also reports on the association of medulloblastoma in germline genetic disorders such as Gorlin syndrome, Li-Fraumeni syndrome, Fanconi anemia, familial adenomatous polyposis (FAP), and others. Genes associated with these disorders are tumor suppressors, and mutations in these genes are often loss of function sequence variants (e.g. premature protein termination); although missense and copy number variants have also been reported. Variants in these disorders can be inherited, but can also occur as de novo mutations. Pathogenic variants have also been observed in other germline genes that increase medulloblastoma risk. For instance, pathogenic variants in GPR161 have been reported to predispose individuals to pediatric medulloblastoma (Begemann et al. 2020. PubMed ID: 31609649). Germline loss of function variants in ELP1 have also been identified in individuals with medulloblastoma, especially pediatric patients in the SHH subgroup (Waszak et al. 2020. PubMed ID: 32296180).

Clinical Sensitivity - Sequencing with CNV PGxome

Pathogenic variants in genes in this panel have been estimated to be responsible for approximately 5% of medulloblastoma diagnoses (Waszak et al. 2018. PubMed ID: 29753700).

Testing Strategy

This test is performed using Next-Gen sequencing with additional Sanger sequencing as necessary.

This panel typically provides 99.5% coverage of all coding exons of the genes plus 10 bases of flanking noncoding DNA in all available transcripts along with other non-coding regions in which pathogenic variants have been identified at PreventionGenetics or reported elsewhere. We define coverage as ≥20X NGS reads or Sanger sequencing. PGnome panels typically provide slightly increased coverage over the PGxome equivalent. PGnome sequencing panels have the added benefit of additional analysis and reporting of deep intronic regions (where applicable).

Dependent on the sequencing backbone selected for this testing, discounted reflex testing to any other similar backbone-based test is available (i.e., PGxome panel to whole PGxome; PGnome panel to whole PGnome).

Indications for Test

Individuals with a personal or family history of medulloblastoma are candidates. This test is specifically designed for heritable germline mutations and is not appropriate for the detection of somatic mutations in tumor tissue.

myPrevent - Online Ordering

  • The test can be added to your online orders in the Summary and Pricing section.
  • Once the test has been added log in to myPrevent to fill out an online requisition form.
  • PGnome sequencing panels can be ordered via the myPrevent portal only at this time.

Requisition Form

  • A completed requisition form must accompany all specimens.
  • Billing information along with specimen and shipping instructions are within the requisition form.
  • All testing must be ordered by a qualified healthcare provider.

For Requisition Forms, visit our Forms page

If ordering a Duo or Trio test, the proband and all comparator samples are required to initiate testing. If we do not receive all required samples for the test ordered within 21 days, we will convert the order to the most effective testing strategy with the samples available. Prior authorization and/or billing in place may be impacted by a change in test code.
