Jan 10, 2022

The c.1123G>A (p.G375S) alteration is located in exon 5 (coding exon 5) of the KLRG2 gene. This alteration results from a G to A substitution at nucleotide position 1123, causing the glycine (G) at amino acid position 375 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
