The c.20A>G (p.D7G) alteration is located in exon 3 (coding exon 1) of the CYB561A3 gene. This alteration results from a A to G substitution at nucleotide position 20, causing the aspartic acid (D) at amino acid position 7 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
