Genes affected

SEC16A (HGNC:29006): (SEC16 homolog A, endoplasmic reticulum export factor) This gene encodes a protein that forms part of the Sec16 complex. This protein has a role in protein transport from the endoplasmic reticulum (ER) to the Golgi and mediates COPII vesicle formation at the transitional ER. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Feb 2013]

The c.6746C>T (p.A2249V) alteration is located in exon 28 (coding exon 26) of the SEC16A gene. This alteration results from a C to T substitution at nucleotide position 6746, causing the alanine (A) at amino acid position 2249 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
