The c.379A>G (p.M127V) alteration is located in exon 2 (coding exon 2) of the RFPL3 gene. This alteration results from a A to G substitution at nucleotide position 379, causing the methionine (M) at amino acid position 127 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
