Description

The c.317_318delTCinsCT variant (also known as p.I106T), located in coding exon 8 of the TNNT2 gene, results from an in-frame deletion of TC and insertion of CT at nucleotide positions 317 to 318. This results in the substitution of the isoleucine residue for a threonine residue at codon 106, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
