Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations is unusual genetic disease that causes progressive loss of little capillary, inevitably leading to visual wear and tear and a series of mini-strokes in the brain. The preliminary symptoms of visual disruption typically begin in middle age years. Patients with RVCL have a shortened life expectancy and usually have a life span in the variety of 5-20 years after beginning of symptoms. The gene in charge of triggering RVCL-S, called TREX1, codes for the protein of the same name whose two primary functions are to fix DNA and to control a specific type of sugar equipment within cells. A phase II clinical test is currently underway using an antibody drug that is currently FDA-approved for another unusual disease that affects small blood vessels. An unassociated Ashkenazi-Jewish family with the same set of symptoms and pathologic findings was reported a year later [1,2] In 1997, Dr. Joanna Jen described a family of Chinese descent that could trace comparable disease symptoms back three generations [5] In 1990 and 1998 Dutch scientists published a report of a family with a similar disease, however with a background of migraine headaches [6] TREX1 is additionally essential for getting rid of DNA originated from viruses that attack and contaminate human cells. They found that TREX1 was local to a specialized part of cells and that TREX1 levels increased in brain areas affected by loss of blood vessels. Future studies making clear the relationship of TREX1, its role in specific cell types and just how TREX1 regulates the wellness of small blood, vessels may lead to new treatment approaches. The major pathologic process of RVCL-S is that small blood vessels too soon quit; that is, weaken and go away [3] The loss of blood supply influences both the eye and the brain since these organs serve crucial functions and are delicate to even small interruptions in blood flow. Some RVCL-S patients also develop thyroid disease or bone issues triggered by loss of small blood vessels. The proper medical diagnosis can be definitively made to effectively develop if the patient has the disease by genetic screening for mutations in the TREX1 gene on a small blood example. Nonetheless, before obtaining hereditary screening, examination with a genetic therapist that knows with RVCL-S is recommended. Research studies are currently being carried out at the RVCL Research Centers at Washington University School of Medicine in St. Louis and the University of Pennsylvania Perelman School of Medicine in Philadelphia.
