H3K27M test information

Funding for our current H3K27M study has ended. We are optimizing our assay and will be submitting a grant for additional funding soon. Please check back here for updates.

*** We are currently not accepting samples for testing, please check back for updates on our testing program******

Indications for H3K27M mutation testing

• Liquid biopsy confirmation of radiographic diagnosis of diffuse midline glioma, H3K27M variant
• Tissue biopsy confirmation of H3K27M mutation when immunohistochemistry not definitive
• Liquid biopsy confirmation of H3K27M mutation for clinical trial eligibility
• Serial liquid biopsy testing for H3K27M as therapeutic response biomarker in context of clinical trial
