Description

The p.H296Y variant (also known as c.886C>T), located in coding exon 2 of the TERT gene, results from a C to T substitution at nucleotide position 886. The histidine at codon 296 is replaced by tyrosine, an amino acid with similar properties. This amino acid position is conserved. 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.
