The c.5645A>C (p.Y1882S) alteration is located in exon 39 (coding exon 37) of the MYH4 gene. This alteration results from a A to C substitution at nucleotide position 5645, causing the tyrosine (Y) at amino acid position 1882 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
