Genes affected

SEC24C (HGNC:10705): (SEC24 homolog C, COPII coat complex component) The protein encoded by this gene is a member of the SEC24 subfamily of the SEC23/SEC24 family, which is involved in vesicle trafficking. The encoded protein has similarity to yeast Sec24p component of COPII. COPII is the coat protein complex responsible for vesicle budding from the ER. The product of this gene may play a role in shaping the vesicle, as well as in cargo selection and concentration. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.40G>C (p.G14R) alteration is located in exon 3 (coding exon 1) of the SEC24C gene. This alteration results from a G to C substitution at nucleotide position 40, causing the glycine (G) at amino acid position 14 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
