The c.5684C>T (p.T1895M) alteration is located in exon 40 (coding exon 38) of the MYH13 gene. This alteration results from a C to T substitution at nucleotide position 5684, causing the threonine (T) at amino acid position 1895 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
