Advances in Cell and Gene Therapy are creating a new revolution in medicine. Early pioneers have advanced our ability to program and modify genes. They have made substantial and dramatic progress, but most of what we can deliver is yet to come.

GeneTether has developed a proprietary method to conjugate, or “tether,” donor DNA templates to CRISPR/Cas9 and other nucleases. We refer to this as our DNA Template-Nuclease-Tethering, or TNT™, Platform.

Our Executive Team

GeneTether’s leadership consists of senior individuals with strong track records in building life sciences companies at all stages of growth.
