The c.5423C>T (p.A1808V) alteration is located in exon 37 (coding exon 35) of the MYH13 gene. This alteration results from a C to T substitution at nucleotide position 5423, causing the alanine (A) at amino acid position 1808 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
