The c.641G>C (p.G214A) alteration is located in exon 1 (coding exon 1) of the KLRG2 gene. This alteration results from a G to C substitution at nucleotide position 641, causing the glycine (G) at amino acid position 214 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
