Ambry Genetics

Nov 13, 2024

The c.2410G>A (p.V804I) alteration is located in exon 16 (coding exon 15) of the DENND2C gene. This alteration results from a G to A substitution at nucleotide position 2410, causing the valine (V) at amino acid position 804 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
