The c.756C>G (p.D252E) alteration is located in exon 6 (coding exon 6) of the DENND4C gene. This alteration results from a C to G substitution at nucleotide position 756, causing the aspartic acid (D) at amino acid position 252 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
