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.

The c.587G>T (p.G196V) alteration is located in exon 5 (coding exon 2) of the MTIF3 gene. This alteration results from a G to T substitution at nucleotide position 587, causing the glycine (G) at amino acid position 196 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
