The c.1843A>G (p.S615G) alteration is located in exon 10 (coding exon 10) of the LONRF2 gene. This alteration results from a A to G substitution at nucleotide position 1843, causing the serine (S) at amino acid position 615 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
