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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.100G>C (p.G34R) alteration is located in exon 2 (coding exon 2) of the STX8 gene. This alteration results from a G to C substitution at nucleotide position 100, causing the glycine (G) at amino acid position 34 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
