The c.5291C>T (p.T1764M) alteration is located in exon 36 (coding exon 34) of the MYH13 gene. This alteration results from a C to T substitution at nucleotide position 5291, causing the threonine (T) at amino acid position 1764 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
