The c.5378C>T (p.T1793M) 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 5378, causing the threonine (T) at amino acid position 1793 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
