Ambry Genetics

Mar 01, 2024

The c.2350G>A (p.A784T) 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 2350, causing the alanine (A) at amino acid position 784 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
