Ambry Genetics

Oct 18, 2021

The c.3515G>T (p.G1172V) alteration is located in exon 1 (coding exon 1) of the IRS1 gene. This alteration results from a G to T substitution at nucleotide position 3515, causing the glycine (G) at amino acid position 1172 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
