Jul 06, 2021

The c.901G>A (p.E301K) alteration is located in exon 3 (coding exon 3) of the KLRG2 gene. This alteration results from a G to A substitution at nucleotide position 901, causing the glutamic acid (E) at amino acid position 301 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
