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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.917G>A (p.R306H) alteration is located in exon 9 (coding exon 9) of the SCAMP3 gene. This alteration results from a G to A substitution at nucleotide position 917, causing the arginine (R) at amino acid position 306 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
