The c.5534G>C (p.S1845T) alteration is located in exon 39 (coding exon 39) of the MYH15 gene. This alteration results from a G to C substitution at nucleotide position 5534, causing the serine (S) at amino acid position 1845 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
