The c.1346A>G (p.N449S) alteration is located in exon 10 (coding exon 10) of the ACSM1 gene. This alteration results from a A to G substitution at nucleotide position 1346, causing the asparagine (N) at amino acid position 449 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
