Genes affected

SEC24A (HGNC:10703): (SEC24 homolog A, COPII coat complex component) The protein encoded by this gene belongs to a family of proteins that are homologous to yeast Sec24. This protein is a component of coat protein II (COPII)-coated vesicles that mediate protein transport from the endoplasmic reticulum. COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the golgi complex. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

The c.352A>C (p.T118P) alteration is located in exon 2 (coding exon 2) of the SEC24A gene. This alteration results from a A to C substitution at nucleotide position 352, causing the threonine (T) at amino acid position 118 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
