Genes affected

TLX2 (HGNC:5057): (T cell leukemia homeobox 2) This gene is a member of an orphan homeobox-containing transcription factor family. Studies of the mouse ortholog have shown that the encoded protein is crucial for the development of the enteric nervous system; in humans, loss-of-function may play a role in tumorigenesis of gastrointestinal stromal tumors.
