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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 18-45852660-C-T is Benign according to our data. Variant chr18-45852660-C-T is described in ClinVar as [Benign]. Clinvar id is 402831.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr18-45852660-C-T is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.16 is higher than 0.05.
