The c.364G>A (p.V122M) alteration is located in exon 4 (coding exon 3) of the MPG gene. This alteration results from a G to A substitution at nucleotide position 364, causing the valine (V) at amino acid position 122 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
