The c.296G>A (p.R99Q) alteration is located in exon 4 (coding exon 3) of the DENND3 gene. This alteration results from a G to A substitution at nucleotide position 296, causing the arginine (R) at amino acid position 99 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
