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.901T>C (p.C301R) alteration is located in exon 7 (coding exon 6) of the SEC22C gene. This alteration results from a T to C substitution at nucleotide position 901, causing the cysteine (C) at amino acid position 301 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
