Ambry Genetics

Nov 24, 2024

The c.1117G>A (p.D373N) alteration is located in exon 12 (coding exon 12) of the DENND6A gene. This alteration results from a G to A substitution at nucleotide position 1117, causing the aspartic acid (D) at amino acid position 373 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
