Genes affected

MPV17 (HGNC:7224): (mitochondrial inner membrane protein MPV17) This gene encodes a mitochondrial inner membrane protein that is implicated in the metabolism of reactive oxygen species. Mutations in this gene have been associated with the hepatocerebral form of mitochondrial DNA depletion syndrome (MDDS). [provided by RefSeq, Jul 2008]

MPV17 Gene-Disease associations (from GenCC):

• mitochondrial disease

  Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
• mitochondrial DNA depletion syndrome 6 (hepatocerebral type)

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: G2P, Labcorp Genetics (formerly Invitae), Orphanet, Ambry Genetics
• Charcot-Marie-Tooth disease, axonal, type 2EE

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
