The c.3785G>A (p.G1262E) alteration is located in exon 24 (coding exon 23) of the DENND4B gene. This alteration results from a G to A substitution at nucleotide position 3785, causing the glycine (G) at amino acid position 1262 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
