The c.518A>C (p.E173A) alteration is located in exon 6 (coding exon 5) of the ACTR3C gene. This alteration results from a A to C substitution at nucleotide position 518, causing the glutamic acid (E) at amino acid position 173 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
