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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.12268072).
• BP6: Variant 2-27309901-G-C is Benign according to our data. Variant chr2-27309901-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 388884.Status of the report is criteria_provided_single_submitter, 1 stars.
