Genes affected

SEC22A (HGNC:20260): (SEC22 homolog A, vesicle trafficking protein) The protein encoded by this gene belongs to the member of the SEC22 family of vesicle trafficking proteins. This protein has similarity to rat SEC22 and may act in the early stages of the secretory pathway. [provided by RefSeq, Nov 2008]

SEC22A links:

PDIA5 (HGNC:24811): (protein disulfide isomerase family A member 5) This gene encodes a member of the disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins that catalyze protein folding and thiol-disulfide interchange reactions. The encoded protein has an N-terminal ER-signal sequence, three catalytically active thioredoxin (TRX) domains, a TRX-like domain, and a C-terminal ER-retention sequence. The N-terminal TRX-like domain is the primary binding site for the major ER chaperone calreticulin and possibly other proteins and substrates as well. Alternative splicing results in multiple protein- and non-protein-coding transcript variants. [provided by RefSeq, Dec 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.178A>G (p.I60V) alteration is located in exon 2 (coding exon 1) of the SEC22A gene. This alteration results from a A to G substitution at nucleotide position 178, causing the isoleucine (I) at amino acid position 60 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
