Genes affected

GOSR2 (HGNC:4431): (golgi SNAP receptor complex member 2) This gene encodes a trafficking membrane protein which transports proteins among the medial- and trans-Golgi compartments. Due to its chromosomal location and trafficking function, this gene may be involved in familial essential hypertension. [provided by RefSeq, Mar 2016]

The c.509A>G (p.N170S) alteration is located in exon 6 (coding exon 6) of the GOSR2 gene. This alteration results from a A to G substitution at nucleotide position 509, causing the asparagine (N) at amino acid position 170 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 170 of the GOSR2 protein (p.Asn170Ser). This variant is present in population databases (rs150907052, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with GOSR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 205631). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant 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. -
