The c.3607G>C (p.G1203R) alteration is located in exon 18 (coding exon 17) of the AKNA gene. This alteration results from a G to C substitution at nucleotide position 3607, causing the glycine (G) at amino acid position 1203 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
