Genes affected

SCAMP3 (HGNC:10565): (secretory carrier membrane protein 3) This gene encodes an integral membrane protein that belongs to the secretory carrier membrane protein family. The encoded protein functions as a carrier to the cell surface in post-golgi recycling pathways. This protein is also involved in protein trafficking in endosomal pathways. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, May 2011]

The c.797T>C (p.L266P) alteration is located in exon 8 (coding exon 8) of the SCAMP3 gene. This alteration results from a T to C substitution at nucleotide position 797, causing the leucine (L) at amino acid position 266 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
