Jul 12, 2022

The c.508G>A (p.E170K) alteration is located in exon 3 (coding exon 3) of the CD300C gene. This alteration results from a G to A substitution at nucleotide position 508, causing the glutamic acid (E) at amino acid position 170 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
