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 GeneticsAug 12, 2021The c.847G>A (p.A283T) alteration is located in exon 8 (coding exon 8) of the SCAMP3 gene. This alteration results from a G to A substitution at nucleotide position 847, causing the alanine (A) at amino acid position 283 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
