Description

The c.325C>T (p.H109Y) alteration is located in exon 9 (coding exon 8) of the TNNT2 gene. This alteration results from a C to T substitution at nucleotide position 325, causing the histidine (H) at amino acid position 109 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
