What is the Choroideremia Research Foundation?

The Choroideremia Research Foundation (CRF) is the largest organization in the world focused on the search for a cure for Choroideremia (CHM).  The Foundation raises funds to support research programs that either focus specifically on Choroideremia or that have application to multiple retinal diseases, of which CHM is included.  The CRF was founded in 2000 by a small group of individuals affected with CHM and their families.

CRF Timeline

What is Choroideremia?

Choroideremia (CHM) is a rare inherited disorder that causes progressive vision loss, ultimately leading to complete blindness.  The first symptom is generally night-blindness, followed by vision loss in the mid-periphery. These “blind spots” appear in an irregular ring, only leaving patches of peripheral vision, while central vision is still maintained. Over time the peripheral vision loss extends in both directions leading to “tunnel vision” and eventually complete loss of sight.  The genetic defect causing the disease occurs on the X chromosome.  As a result, men are predominantly affected by CHM; women, who in rare cases can show full-blown signs of CHM, typically are carriers of the disease.  CHM is estimated to affect 1 in 50,000 individuals, making it a rare disease.

What is the prognosis for people with Choroideremia?

People with Choroideremia (CHM) begin to demonstrate signs of vision impairment in their childhood, most notably with poor night vision.  Peripheral vision loss begins as “blind spots” which grow in size and eventually coalesce into an irregular ring, leaving affected individuals with tunnel vision.  While progression of vision loss varies to some degree, most individuals with CHM are legally blind in their 30’s.  Central vision loss eventually deteriorates as well, eventually leading to complete blindness.  No treatment or cure has been developed to this date to slow down or halt vision loss from CHM.

Where does the Choroideremia Research Foundation get its funding?

The Choroideremia Research Foundation (CRF) is supported through donations from individuals and corporations.  The CRF’s primary source of funding is a grassroots network of members who organize and support fundraisers across the United States and internationally.  Donations to the CRF have directly supported the pre-clinical development of an experimental gene therapy treatment currently in clinical trials in the United Kingdom, in addition to others soon to begin in the United States and Canada.
