Ambry Genetics

Jun 29, 2023

The c.1220G>T (p.R407I) alteration is located in exon 11 (coding exon 11) of the DENND2D gene. This alteration results from a G to T substitution at nucleotide position 1220, causing the arginine (R) at amino acid position 407 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
