Genes affected

MTRF1 (HGNC:7469): (mitochondrial translation release factor 1) The protein encoded by this gene was determined by in silico methods to be a mitochondrial protein with similarity to the peptide chain release factors (RFs) discovered in bacteria and yeast. The peptide chain release factors direct the termination of translation in response to the peptide chain termination codons. Initially thought to have a role in the termination of mitochondria protein synthesis, a recent publication found no mitochondrial translation release functionality. Multiple alternatively spliced transcript variants have been suggested by mRNA and EST data; however, their full-length natures are not clear. [provided by RefSeq, Jul 2008]

The c.614G>A (p.R205Q) alteration is located in exon 5 (coding exon 4) of the MTRF1 gene. This alteration results from a G to A substitution at nucleotide position 614, causing the arginine (R) at amino acid position 205 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
