The c.520A>G (p.R174G) alteration is located in exon 2 (coding exon 2) of the METRNL gene. This alteration results from a A to G substitution at nucleotide position 520, causing the arginine (R) at amino acid position 174 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
