Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_004294.4(MTRF1):​c.1151G>T​(p.Arg384Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 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. R384Q) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: MTRF1 NM_004294.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.48
• Publications: 2 publications found

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]

KBTBD6-DT (HGNC:56824): (KBTBD6 divergent transcript)

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.928
