The c.272A>G (p.Q91R) alteration is located in exon 4 (coding exon 2) of the ACSM2B gene. This alteration results from a A to G substitution at nucleotide position 272, causing the glutamine (Q) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
