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]

Collection Method: clinical testing

The c.47T>C (p.L16P) alteration is located in exon 2 (coding exon 2) of the SEC61A2 gene. This alteration results from a T to C substitution at nucleotide position 47, causing the leucine (L) at amino acid position 16 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
