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]

VPS53 Gene-Disease associations (from GenCC):

• pontocerebellar hypoplasia, type 13

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
• progressive cerebello-cerebral atrophy

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP7: Synonymous conserved (PhyloP=-2.32 with no splicing effect.
