In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as no classification for the single variant (no stars).

• Frequency: Genomes: not found (cov: 32)
• Consequence: EPG5 NM_020964.3 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.931

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
