The c.163G>A (p.V55M) alteration is located in exon 3 (coding exon 1) of the LETM2 gene. This alteration results from a G to A substitution at nucleotide position 163, causing the valine (V) at amino acid position 55 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
