Genes affected

SSR1 (HGNC:11323): (signal sequence receptor subunit 1) The signal sequence receptor (SSR) is a glycosylated endoplasmic reticulum (ER) membrane receptor associated with protein translocation across the ER membrane. The SSR consists of 2 subunits, a 34-kD glycoprotein encoded by this gene and a 22-kD glycoprotein. This gene generates several mRNA species as a result of complex alternative polyadenylation. This gene is unusual in that it utilizes arrays of polyA signal sequences that are mostly non-canonical. Multiple transcript variants encoding different isoforms have been found for this gene.

Collection Method:clinical testing

The c.644C>T (p.A215V) alteration is located in exon 6 (coding exon 6) of the SSR1 gene. This alteration results from a C to T substitution at nucleotide position 644, causing the alanine (A) at amino acid position 215 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
