Ambry Genetics

May 04, 2022

The c.2121A>G (p.I707M) alteration is located in exon 14 (coding exon 13) of the DENND2C gene. This alteration results from a A to G substitution at nucleotide position 2121, causing the isoleucine (I) at amino acid position 707 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
