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.548T>A (p.L183H) alteration is located in exon 6 (coding exon 6) of the SCAMP3 gene. This alteration results from a T to A substitution at nucleotide position 548, causing the leucine (L) at amino acid position 183 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
