Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_Strong BP6_Very_Strong BS1 BS2

The NM_020964.3(EPG5):​c.5954G>A​(p.Arg1985Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00365 in 1,613,746 control chromosomes in the GnomAD database, including 67 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1985W) has been classified as Uncertain significance.

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

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, Orphanet, G2P

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002965033).
• BP6: Variant 18-45876331-C-T is Benign according to our data. Variant chr18-45876331-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 466260.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0124 (1882/152234) while in subpopulation AFR AF = 0.0368 (1527/41540). AF 95% confidence interval is 0.0352. There are 33 homozygotes in GnomAd4. There are 892 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 33 AR gene
