Ambry Genetics

Feb 27, 2023

The c.880A>G (p.I294V) alteration is located in exon 5 (coding exon 5) of the ARMT1 gene. This alteration results from a A to G substitution at nucleotide position 880, causing the isoleucine (I) at amino acid position 294 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
