The c.961A>G (p.M321V) alteration is located in exon 3 (coding exon 1) of the MTERF2 gene. This alteration results from a A to G substitution at nucleotide position 961, causing the methionine (M) at amino acid position 321 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
