Genes affected

SSR3 (HGNC:11325): (signal sequence receptor subunit 3) The signal sequence receptor (SSR) is a glycosylated endoplasmic reticulum (ER) membrane receptor associated with protein translocation across the ER membrane. The SSR is comprised of four membrane proteins/subunits: alpha, beta, gamma, and delta. The first two are glycosylated subunits and the latter two are non-glycosylated subunits. This gene encodes the gamma subunit, which is predicted to span the membrane four times. [provided by RefSeq, Aug 2010]

The c.409T>G (p.S137A) alteration is located in exon 4 (coding exon 4) of the SSR3 gene. This alteration results from a T to G substitution at nucleotide position 409, causing the serine (S) at amino acid position 137 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
