The c.1298C>T (p.T433I) alteration is located in exon 12 (coding exon 10) of the ACSM2B gene. This alteration results from a C to T substitution at nucleotide position 1298, causing the threonine (T) at amino acid position 433 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
