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.331A>G (p.T111A) alteration is located in exon 4 (coding exon 4) of the GOSR2 gene. This alteration results from a A to G substitution at nucleotide position 331, causing the threonine (T) at amino acid position 111 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine with alanine at codon 111 of the GOSR2 protein (p.Thr111Ala). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and alanine. This variant is present in population databases (rs780448159, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with GOSR2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
