Ambry Genetics

Jan 02, 2024

The c.2422G>A (p.D808N) alteration is located in exon 13 (coding exon 13) of the DENND2A gene. This alteration results from a G to A substitution at nucleotide position 2422, causing the aspartic acid (D) at amino acid position 808 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
