Ambry Genetics

Aug 03, 2022

The c.2242G>A (p.V748I) alteration is located in exon 15 (coding exon 15) of the IMMT gene. This alteration results from a G to A substitution at nucleotide position 2242, causing the valine (V) at amino acid position 748 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
