Genes affected

VPS53 (HGNC:25608): (VPS53 subunit of GARP complex) Involved in endocytic recycling and retrograde transport, endosome to Golgi. Acts upstream of or within lysosomal transport. Located in several cellular components, including Golgi apparatus; perinuclear region of cytoplasm; and recycling endosome. Part of EARP complex and GARP complex. Implicated in pontocerebellar hypoplasia type 2E. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.268 is higher than 0.05.
