Ambry Genetics

Nov 22, 2023

The c.82G>A (p.E28K) alteration is located in exon 2 (coding exon 2) of the GMNC gene. This alteration results from a G to A substitution at nucleotide position 82, causing the glutamic acid (E) at amino acid position 28 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
