The c.862G>A (p.V288I) alteration is located in exon 5 (coding exon 4) of the MPG gene. This alteration results from a G to A substitution at nucleotide position 862, causing the valine (V) at amino acid position 288 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
