Genes affected

EPG5 (HGNC:29331): (ectopic P-granules 5 autophagy tethering factor) This gene encodes a large coiled coil domain-containing protein that functions in autophagy during starvation conditions. Mutations in this gene cause Vici syndrome. [provided by RefSeq, Aug 2015]

This sequence change replaces glycine with cysteine at codon 1563 of the EPG5 protein (p.Gly1563Cys). The glycine residue is moderately conserved and there is a large physicochemical difference between glycine and cysteine. This variant is present in population databases (rs751554863, ExAC 0.004%). This variant has not been reported in the literature in individuals affected with EPG5-related conditions. 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. -
