Genes affected

SEC61A2 (HGNC:17702): (SEC61 translocon subunit alpha 2) The protein encoded by this gene has similarity to a mouse protein which suggests a role in the insertion of secretory and membrane polypeptides into the endoplasmic reticulum. It may also be required for the assembly of membrane and secretory proteins. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2008]

The c.1084G>A (p.V362I) alteration is located in exon 10 (coding exon 10) of the SEC61A2 gene. This alteration results from a G to A substitution at nucleotide position 1084, causing the valine (V) at amino acid position 362 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
