The c.472A>T (p.M158L) alteration is located in exon 4 (coding exon 1) of the MIOS gene. This alteration results from a A to T substitution at nucleotide position 472, causing the methionine (M) at amino acid position 158 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
