The c.640C>G (p.Q214E) alteration is located in exon 7 (coding exon 6) of the DENND3 gene. This alteration results from a C to G substitution at nucleotide position 640, causing the glutamine (Q) at amino acid position 214 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
