The c.1154C>T (p.T385M) alteration is located in exon 10 (coding exon 8) of the ACSM2B gene. This alteration results from a C to T substitution at nucleotide position 1154, causing the threonine (T) at amino acid position 385 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
