Ambry Genetics

May 09, 2023

The c.296A>T (p.E99V) alteration is located in exon 4 (coding exon 4) of the GMNC gene. This alteration results from a A to T substitution at nucleotide position 296, causing the glutamic acid (E) at amino acid position 99 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
