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]

Jul 09, 2024

The c.484G>A (p.D162N) alteration is located in exon 7 (coding exon 7) of the STX2 gene. This alteration results from a G to A substitution at nucleotide position 484, causing the aspartic acid (D) at amino acid position 162 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
