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]

The c.4559C>T (p.P1520L) alteration is located in exon 26 (coding exon 26) of the EPG5 gene. This alteration results from a C to T substitution at nucleotide position 4559, causing the proline (P) at amino acid position 1520 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1520 of the EPG5 protein (p.Pro1520Leu). This variant is present in population databases (rs375867560, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with EPG5-related conditions. ClinVar contains an entry for this variant (Variation ID: 466251). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt EPG5 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. -
