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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.149G>A (p.R50Q) alteration is located in exon 2 (coding exon 1) of the SEC22C gene. This alteration results from a G to A substitution at nucleotide position 149, causing the arginine (R) at amino acid position 50 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
