The c.184G>C (p.G62R) alteration is located in exon 1 (coding exon 1) of the ISG20L2 gene. This alteration results from a G to C substitution at nucleotide position 184, causing the glycine (G) at amino acid position 62 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
