Genes affected
STX2 (HGNC:3403): (syntaxin 2) The product of this gene belongs to the syntaxin/epimorphin family of proteins. The syntaxins are a large protein family implicated in the targeting and fusion of intracellular transport vesicles. The product of this gene regulates epithelial-mesenchymal interactions and epithelial cell morphogenesis and activation. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2024The c.338G>A (p.R113Q) alteration is located in exon 5 (coding exon 5) of the STX2 gene. This alteration results from a G to A substitution at nucleotide position 338, causing the arginine (R) at amino acid position 113 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
