Genes affected

SEC13 (HGNC:10697): (SEC13 homolog, nuclear pore and COPII coat complex component) The protein encoded by this gene belongs to the SEC13 family of WD-repeat proteins. It is a constituent of the endoplasmic reticulum and the nuclear pore complex. It has similarity to the yeast SEC13 protein, which is required for vesicle biogenesis from endoplasmic reticulum during the transport of proteins. Multiple alternatively spliced transcript variants have been found. [provided by RefSeq, Oct 2008]

Collection Method: clinical testing

The c.647G>A (p.R216Q) alteration is located in exon 7 (coding exon 7) of the SEC13 gene. This alteration results from a G to A substitution at nucleotide position 647, causing the arginine (R) at amino acid position 216 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
