Description

The p.T26M variant (also known as c.77C>T), located in coding exon 1 of the TERT gene, results from a C to T substitution at nucleotide position 77. The threonine at codon 26 is replaced by methionine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
