Genes affected

SEC22C (HGNC:16828): (SEC22 homolog C, vesicle trafficking protein) This gene encodes a member of the SEC22 family of vesicle trafficking proteins. The encoded protein is localized to the endoplasmic reticulum and may play a role in the early stages of ER-Golgi protein trafficking. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

The c.683T>C (p.L228P) alteration is located in exon 6 (coding exon 5) of the SEC22C gene. This alteration results from a T to C substitution at nucleotide position 683, causing the leucine (L) at amino acid position 228 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
