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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2023The c.343G>A (p.G115R) alteration is located in exon 1 (coding exon 1) of the TLX2 gene. This alteration results from a G to A substitution at nucleotide position 343, causing the glycine (G) at amino acid position 115 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
