The c.2222G>A (p.R741Q) alteration is located in exon 15 (coding exon 14) of the DENND2C gene. This alteration results from a G to A substitution at nucleotide position 2222, causing the arginine (R) at amino acid position 741 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
