The c.686A>G (p.N229S) alteration is located in exon 2 (coding exon 2) of the RMDN2 gene. This alteration results from a A to G substitution at nucleotide position 686, causing the asparagine (N) at amino acid position 229 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
