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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 16 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_002437.5
PM5
Other missense variant is known to change same aminoacid residue: Variant chr2-27312576-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 2888969.Status of the report is criteria_provided_single_submitter, 1 stars.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.966
PP5
Variant 2-27312576-G-A is Pathogenic according to our data. Variant chr2-27312576-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 38355.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
