Ambry Genetics

Feb 05, 2024

The c.405A>G (p.I135M) alteration is located in exon 3 (coding exon 3) of the PLXDC2 gene. This alteration results from a A to G substitution at nucleotide position 405, causing the isoleucine (I) at amino acid position 135 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
