Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_152912.5(MTIF3):c.413A>C(p.Gln138Pro) variant causes a missense change. The variant allele was found at a frequency of 0.00000929 in 1,614,124 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q138R) has been classified as Likely benign.

Genes affected

MTIF3 (HGNC:29788): (mitochondrial translational initiation factor 3) This gene encodes a translation initiation factor that is involved in mitochondrial protein synthesis. Polymorphism in this gene is associated with the onset of Parkinson's disease. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 5.
