The c.473T>C (p.M158T) alteration is located in exon 3 (coding exon 3) of the MYBPH gene. This alteration results from a T to C substitution at nucleotide position 473, causing the methionine (M) at amino acid position 158 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
