A Tel Aviv University researcher has established an apparatus to help Israeli
families with rare genetic defects undergo testing and, it is hoped, eventually
The project will be funded by visitors to a website
with personal stories of patients who choose to donate toward helping a specific
family. Such testing is not in the basket of health services funded by health
taxes and government subsidies.
The effort was announced on Wednesday on
the eve of the International Rare Diseases Day, which will be marked around the
world on Thursday.
The method of funding is called “crowd-sourcing,”
referring to a collective effort by individuals who network and pool their
money, especially via the Internet, to give financial support to projects
initiated by other people or organizations.
As these “orphan diseases”
affect only a small number of people, drug companies and governments spend
little money to research rare genetic disorders. The US-based nonprofit Rare
Genomics Institute (RGI) is working to address this problem by “crowd-funding” –
allowing people to donate online to cover the genetic testing of children who
are struggling with rare diseases.
Dr. Noam Shomron of Tel Aviv
University’s Sackler Faculty of Medicine has adopted the RGI idea and set up an
Israeli branch. The organization has just launched its first online appeal for
two Israeli children.
As many as 250 million people around the world
suffer from orphan diseases; however, since there are so many but so few people
suffer from a specific one, there is little hope for diagnosis or

affected child and their relatives, depending on the family’s genetic history
and the genetics of the disease, said Shomron. This allows families to avoid the

One family, for example, has been plagued for generations by
what appears to be mental retardation – but the medical cause of this condition
remains a mystery.
“They have been living for many years without knowing
what causes this problem in their family. They don’t know whether their DNA is
the cause – and if it is, what mutation causes it,” the Tel Aviv University
Once the genetic testing has been completed, RGIIsrael’s
doctors will meet with each family to discuss the results. The support will end

together to investigate these rare diseases.

sense of relief and hope and also assists the physicians in creating better
treatment plans. In a few cases, RGI’s work has even led to a successful

defective gene, who underwent a stem cell transplant and was completely
