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]

SCAMP3 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.682 is higher than 0.05.
