The c.920A>C (p.E307A) alteration is located in exon 7 (coding exon 6) of the RMDN3 gene. This alteration results from a A to C substitution at nucleotide position 920, causing the glutamic acid (E) at amino acid position 307 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
