Collection Method: clinical testing

The c.971C>G (p.S324C) alteration is located in exon 8 (coding exon 6) of the ACSM2B gene. This alteration results from a C to G substitution at nucleotide position 971, causing the serine (S) at amino acid position 324 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
