The c.1310A>G (p.E437G) alteration is located in exon 11 (coding exon 11) of the DENND2D gene. This alteration results from a A to G substitution at nucleotide position 1310, causing the glutamic acid (E) at amino acid position 437 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
