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]

Observed with a second variant on the opposite allele (in trans) in a patient in published literature (Larsen et al., 2018) with hypotonia, progressive muscle weakness, seizures, and -dystroglycan hypoglycosylation; Published functional studies demonstrate a damaging effect (Praschberger et al., 2017; Volker et al., 2017); Not observed at a significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 27342741, 21549339, 28978487, 28982678, 27618868, 24458321, 25326637, 23449775, 29431110, 28264719, 29855340, 31692161, 30363482, 32105965, 33639315) -

Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with tryptophan, which is neutral and slightly polar, at codon 144 of the GOSR2 protein (p.Gly144Trp). This variant is present in population databases (rs387906881, gnomAD 0.01%). This missense change has been observed in individuals with progressive myoclonic epilepsy (PMID: 21549339, 23449775). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 30406). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects GOSR2 function (PMID: 21549339, 28982678). For these reasons, this variant has been classified as Pathogenic. -
