Genes affected

SCAMP2 (HGNC:10564): (secretory carrier membrane protein 2) This gene product belongs to the SCAMP family of proteins which are secretory carrier membrane proteins. They function as carriers to the cell surface in post-golgi recycling pathways. Different family members are highly related products of distinct genes, and are usually expressed together. These findings suggest that the SCAMPs may function at the same site during vesicular transport rather than in separate pathways. Alternate splicing results in multiple transcript variants.

May 03, 2023

The c.75G>C (p.Q25H) alteration is located in exon 2 (coding exon 2) of the SCAMP2 gene. This alteration results from a G to C substitution at nucleotide position 75, causing the glutamine (Q) at amino acid position 25 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
