Genes affected

VPS13C (HGNC:23594): (vacuolar protein sorting 13 homolog C) Involved in mitochondrion organization and negative regulation of parkin-mediated stimulation of mitophagy in response to mitochondrial depolarization. Located in cytosol and mitochondrial outer membrane. Implicated in Parkinson's disease 23. [provided by Alliance of Genome Resources, Apr 2022]

VPS13C Gene-Disease associations (from GenCC):

• autosomal recessive early-onset Parkinson disease 23

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Genomics England PanelApp
• young-onset Parkinson disease

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• schizophrenia

  Inheritance: Unknown Classification: NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae)
