Ambry Genetics

Feb 28, 2024

The c.1099A>G (p.I367V) alteration is located in exon 3 (coding exon 1) of the PRSS35 gene. This alteration results from a A to G substitution at nucleotide position 1099, causing the isoleucine (I) at amino acid position 367 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
