What Is Sarcoidosis?
9. Is Sarcoidosis Genetic or Contagious?
Sarcoidosis is not contagious. However, the genetic correlation is a little more complicated. There are currently no screening options for the disease because the likelihood of relatives getting the disease is too low. Although, research suggests that if a first- or second-degree relative has the presence of sarcoidosis, there is an increased risk to family members. In fact, some studies suggest this genetic correlation increase likelihood five-fold.
Still, the role of heredity in the development of the disorder is still uncertain. Researchers do know that certain genes play a role in susceptibility. However, the evolution and effect of the disease depend on how those genes combine. Unfortunately, sarcoidosis is still a mystery. While physicians and scientists are learning more every day, there is still a lot of work to be done before a definitive cause can be determined.
