The c.3188A>G (p.E1063G) alteration is located in exon 7 (coding exon 7) of the MTUS2 gene. This alteration results from a A to G substitution at nucleotide position 3188, causing the glutamic acid (E) at amino acid position 1063 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
