In the summer iof 2004, research funded by JDRF revealed that a mutation of the SUMO-4 gene is a strong factor in the development of type 1 diabetes and the potential associated complications, such as kidney failure.

The gene called SUMO-4 is responsible for signaling the proteins that regulate the intensity and duration of the immune response. When the gene is mutated, it has an increased response to the stimulants of the immune system, that cause it to overreact. This overreaction results in a person's inability to distinguish between self and foreign cells, thus causing type 1 diabetes. The mutated SUMO-4 gene may exacerbate the inflammatory process, influencing the complications of diabetes.

The most influential genes in the development of type 1 diabetes are found in the HLA or human leukocyte antigen region. These genes help regulate the immune system by guiding it to differentiate between self and non-self. Variants of the DR and DQ genes in the HLA region are found in 95% of type 1 diabetics. Another gene that increases the chances of developing type 1 diabetes has been found in the region immediately preceding the insulin gene. This region contains a VNTR or variable number of tandem repeats. This refers to specific chemical bases that make up DNA. Inheritance of certain VNTR's increases the risk of developing type 1 diabetes.

Again I reiterate this research was unveiled in 2004. SUMO-4 was identified as a prime target to control the inflammatory process leading to the destruction of islets. As I search Google for, "sumo4, drugs, JDRF" I am terribly disappointed to see that my yearning for answers remains unrequited. Did SUMO-4 fall too hard too fast?
