Genetic Factors behind Gastrointestinal Stromal Tumors
Gastrointestinal stromal tumors (GISTs) are predominantly caused by genetic abnormalities occurring in two crucial genes, namely KIT and PDGFRA. These genes are responsible for transmitting signals within cells, regulating various processes including cell growth, division, and more. Any mutation in these genes can significantly escalate the chances of uncontrolled cell growth, leading to the formation of GISTs.
Inherited vs. Non-inherited Gastrointestinal Stromal Tumors
Gastrointestinal stromal tumors (GISTs) can be classified as either inherited or non-inherited. While both types involve the same genes, the mutation in the non-inherited form occurs randomly. Individuals with the non-inherited form typically develop a single tumor, whereas those with the inherited form are more likely to have multiple GISTs and experience a greater number of symptoms.
