The c.803C>G (p.P268R) alteration is located in exon 6 (coding exon 5) of the ACSM3 gene. This alteration results from a C to G substitution at nucleotide position 803, causing the proline (P) at amino acid position 268 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
