Ambry Genetics

Oct 25, 2022

The c.118A>G (p.M40V) alteration is located in exon 2 (coding exon 2) of the SPINT3 gene. This alteration results from a A to G substitution at nucleotide position 118, causing the methionine (M) at amino acid position 40 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
