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]

This sequence change affects the initiator methionine of the GOSR2 mRNA. The next in-frame methionine is located at codon 19. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with GOSR2-related conditions. This variant is not present in population databases (ExAC no frequency). -
