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]

EPG5 Gene-Disease associations (from GenCC):

• Vici syndrome

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant 18-45880159-G-A is Benign according to our data. Variant chr18-45880159-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 466255.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.583 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0038 (578/152286) while in subpopulation AFR AF = 0.00864 (359/41572). AF 95% confidence interval is 0.0079. There are 3 homozygotes in GnomAd4. There are 309 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 3 AR gene
