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]

This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 123 of the SSR3 protein (p.Ser123Phe). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SSR3-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬¨‚Ä†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
