The c.739G>C (p.E247Q) alteration is located in exon 5 (coding exon 4) of the RMDN3 gene. This alteration results from a G to C substitution at nucleotide position 739, causing the glutamic acid (E) at amino acid position 247 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
