The c.973A>G (p.T325A) alteration is located in exon 10 (coding exon 10) of the MICU2 gene. This alteration results from a A to G substitution at nucleotide position 973, causing the threonine (T) at amino acid position 325 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
