Genes affected

VPS25 (HGNC:28122): (vacuolar protein sorting 25 homolog) This gene encodes a protein that is a subunit of the endosomal sorting complex required for transport II (ESCRT-II). This protein complex functions in sorting of ubiquitinated membrane proteins during endocytosis. A pseudogene of this gene is present on chromosome 1. [provided by RefSeq, Jul 2013]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.001820296).
• BP6: Variant 17-42774672-A-G is Benign according to our data. Variant chr17-42774672-A-G is described in ClinVar as Benign. ClinVar VariationId is 791412.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 = 0.0103 (1562/152132) while in subpopulation AFR AF = 0.0354 (1471/41502). AF 95% confidence interval is 0.0339. There are 25 homozygotes in GnomAd4. There are 704 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAd4 at 1562 AD gene.
