Jul 27, 2022

The c.217G>C (p.A73P) alteration is located in exon 3 (coding exon 2) of the ACSM6 gene. This alteration results from a G to C substitution at nucleotide position 217, causing the alanine (A) at amino acid position 73 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
