The c.1783A>G (p.I595V) alteration is located in exon 12 (coding exon 12) of the RTKN2 gene. This alteration results from a A to G substitution at nucleotide position 1783, causing the isoleucine (I) at amino acid position 595 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
