That statement is "false" since the cause is still sort of unknown. Scientists are still working on figuring out why the immune system incorrectly damages and destroys the insulin-producing beta cells from the pancreas, which is how the type 1 diabetes is developed. However, muted genes are surely not a cause.
Diabetes Mellitus Type 1 is a type of metabolic disorder that results from the bodies inability to produce insulin causing a disorder where patients are insulin dependent. They require insulin or the bodies will be unable to process sugars for energy.</span>
