The RVCL Research Center

Retinal vasculopathy with cerebral leukoencephalopathy (RVCL, also known as RVCL-S or HERNS) is a rare disease that affects 100% of people with mutations in a specific region of the TREX1 gene.  In families affected by RVCL, about half of all family members have the disease.
  • The University of Pennsylvania (Penn) was our nation's first university and medical school. Today, the University of Pennsylvania and its hospital are leading the way in gene therapy.
  • The RVCL Research Center at Penn is performing cutting-edge research. Our goal is to develop precision and personalized therapies for RVCL.
  • We have assembled a team of expert clinicians, researchers, and genetic counselors, who support patients and families with RVCL.

Gene Therapy UpdateGene Therapy Update:

The Miner laboratory can now fully correct TREX1 mutations in cultured cells in the laboratory.  Now the goal is to develop delivery systems, and to test the safety and efficacy of  gene therapy in model systems of RVCL.

Gene Therapy
RVCL is caused by alterations (mutations) in the TREX1 gene. Using gene editing technology, we can now fully correct TREX1 mutations in cells.  Our goal is to turn this into a therapy for RVCL.

Precision and Personalized Medicine at Penn

We partner with patients, physicians, and scientists from around the world in an effort to develop precision and personalized medicines for RVCL. 
Thanks to generous support from The Clayco Foundation, as well as from the families and friends of patients with RVCL, we are pushing forward faster than ever in this effort.
Our team consists of a group of rheumatologists, neurologists, ophthalmologists, genetic counselors, researchers, and research assistants, all with the singular goal of helping you and your family.

What is CRISPR and will it work for RVCL?

We are using a specialized form of CRISPR (gene editing) that corrects the type of mutation found in RVCL.  We are also collaborating with experts on delivery systems, so that we can use CRISPR to treat RVCL. This is an exciting potential treatment option, but using CRISPR to treat RVCL is no small task. Nevertheless, CRISPR is one of the key personalized medicine pathways that we are actively pursuing.
