The c.1049C>G (p.A350G) alteration is located in exon 3 (coding exon 1) of the MTERF2 gene. This alteration results from a C to G substitution at nucleotide position 1049, causing the alanine (A) at amino acid position 350 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
