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]
LRRC37A2 (HGNC:32404): (leucine rich repeat containing 37 member A2) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 207 of the GOSR2 protein (p.Val207Met). This variant is present in population databases (rs780839289, gnomAD 0.02%). 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: 531809). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -
