Description

The p.A279V variant (also known as c.836C>T), located in coding exon 2 of the TERT gene, results from a C to T substitution at nucleotide position 836. The alanine at codon 279 is replaced by valine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
