The c.158A>T (p.H53L) alteration is located in exon 3 (coding exon 1) of the ACSM2B gene. This alteration results from a A to T substitution at nucleotide position 158, causing the histidine (H) at amino acid position 53 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
