The c.820A>G (p.M274V) alteration is located in exon 7 (coding exon 7) of the NEMP2 gene. This alteration results from a A to G substitution at nucleotide position 820, causing the methionine (M) at amino acid position 274 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
