Genes affected

MTERF1 (HGNC:21463): (mitochondrial transcription termination factor 1) This gene encodes a mitochondrial transcription termination factor. This protein participates in attenuating transcription from the mitochondrial genome; this attenuation allows higher levels of expression of 16S ribosomal RNA relative to the tRNA gene downstream. The product of this gene has three leucine zipper motifs bracketed by two basic domains that are all required for DNA binding. There is evidence that, for this protein, the zippers participate in intramolecular interactions that establish the three-dimensional structure required for DNA binding.

The c.784A>G (p.T262A) alteration is located in exon 3 (coding exon 2) of the MTERF1 gene. This alteration results from a A to G substitution at nucleotide position 784, causing the threonine (T) at amino acid position 262 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
