Genes affected

STX8 (HGNC:11443): (syntaxin 8) The gene is a member of the syntaxin family. The encoded protein is involved in protein trafficking from early to late endosomes via vesicle fusion and exocytosis. A related pseudogene has been identified on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Nov 10, 2024

The c.701C>G (p.P234R) alteration is located in exon 8 (coding exon 8) of the STX8 gene. This alteration results from a C to G substitution at nucleotide position 701, causing the proline (P) at amino acid position 234 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
